U5.3 - ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.'

We are getting reports from a fair bit of customers playing our game that it crashes at either random or concurrent points in the game after we've upgraded to 5.3. Some are able to restart the game and then not crash, but others always crash at the same spot. So far, this seems to only happen for users playing on Windows systems (all versions).

All log files from users with this issue outputs the following stack trace:

Are anyone else experiencing this? We've seen other threads/posts about this issue as well, dating back to April of this year and all the way to now (June).
No workarounds or answers as of yet.

Here's a few of those threads:

Thanks.

 

Attached is the output log, crash dump and error log from one of our users encountering this issue. Thanks

 

I emailed a Matthew D from Unity last week. Not sure if you guys are in contact but our costumers are also getting this issue.
All systems affected have AMD A-Series CPU's

 

In our case, this has happened on a few Intel based CPUs as well.
From what Tautvydas Zilys said earlier, it might be that we're actually having slightly different issues. The common thing however, is just that the crash handler failed to locate the point in code where it crashes.

 

I think you're right, hopefully we can make some progress in either case.

 

Any more news on this?
I don't mean to be nagging you, but we're really eager to find out what's happening and possibly fix the issue for our customers not being able to finish our game.

 

We're getting the same thing... The odd thing is that we have installed our game onto multiple copies of identical hardware (50+ at the moment) and this only happens on one. I did notice the RAM level is 94% when it happened, and the game is downloading a large AssetBundle at the time... Could those be related?

@mihaipopescu If it helps, we're using the Intel Compute Sticks, which come with Windows 10, but only 2GB of RAM. Our game is designed for low resource usage, but it does need rather big AssetBundles. If the download caching for bundles isn't great, I could definitely see it running out of RAM... but since those use Flash Memory (I think?), it ought to be able to write it as fast as the network can receive it.

Since our problem only occurred with one of the devices and worked on so many others, we ended up deciding it was likely a defect in the device itself. Not sure if we still have it lying around.

 

It happens on 5.5 too, but I found one thing on 5.5, if I check "Development Build" checkbox then error is not occurring, maybe You could check in Your projects if it's behaving the same and maybe it will give to someone from Unity clue what is changing that it is working with checked and crashed with unchecked that checkbox.

 

I am seeing invalid address issues of my own using an intel(R) Core(TM) i7-6700K CPUGHz 4.00 GHz machine with unity 5.5.0f3

I have traced my issue down to the instantiate call in the Unity API. I commented out my item spawner just to see what happens and i get this same exact issue down the road (hard crash when calling instantiate) when our inventory system attempts to instantiate copies of the same prefab. It is either in my data or some kind of issue in the instantiate call. The object I am attempting to instantiate is a serialized link to a prefab that is packed away inside of a .asset file. I load the .asset file using Resources.Load and then take my loaded object and reference the prefab to be instantiated from there and pass it into instantiate... this reliably crashes to desktop for me (I would be more than happy to upload some files to unity).

I have found that enabling debug mode during building gives me a working build (Can not be used unfortunately due to the console being embedded and other reasons), and I have also found that everything works just fine in the editor. It's just building a game for release (no debug no pdb ect...) that causes the issue.

Here is the really strange thing... I found the .asset that was trying to instantiate an icon prefab before the crash and swapped it's icon prefab with another .asset files icon prefab and it allows me to build my game in non-debug mode and run it with no issues (except for the fact that my item icons are all reversed).

I tried nuking my library folder and rebuilding everything and ensuring that there was no jargon inside my .asset files and none of these worked. I am pretty desperate for a solution at this point.

 

@Tautvydas-Zilys
It may caused by between ParticleSystem and PhysX related issue.

cs detected workaround.

Updated that ^^ thread with my experiences of the issue..

 

So this is kind of an old thread I'm digging up I guess but it's what I found searching. I run a Rust server on a dedicated windows server 2012 r2 machine and for about the last 2 months I get anywhere from 2-6 random crashes a day and nobody including the rust devs seem to be able to tell me anything from my stack traces so I'm trying here as a shot in the dark

========== END OF STACKTRACE ===========

**** Crash! ****

 

Same crash here. Doesn't work with a Development build either (Not responding).

Any update on this guys? Did anyone try Unity 5.6.1 ?

 

I fixed the issue by upgrading my project to Unity 5.6.1

It is definitely an OpenVR related issue. With 5.6.0f3, I could avoid the crash only by:
- removing ALL lights in the scene (or using no Camera)
- or removing "OpenVR" and using "None" from Player Settings (with VR still enabled).

Both were not a solution so I upgraded to 5.6.1 and everything went back to normal.
But I still don't know what triggered that issue in the first place.

The only clue I have: I remember I noticed "None" and "OpenVR" in the VR SDKs list and I decided to remove "None" because I didn't know why it was there. Previously, they both were added automatically by something external (maybe by VRTK Asset, maybe by SteamVR, I'm not sure). When I noticed the crash with the standalone, I tried to add "None" back but the crash was still occurring.

I hope that helps. When I have time, I'll try to "Copy PDB files" and send the result here.

 

I have the same issue in 2017.1 when realtime GI is on and baked GI's lightmapper is progressive

 

Hi,

We have the same issue in 5.3.8 and 5.5.4. I have attached the folder generated after the crash with the .dmp. from a build that contained the PDB files (so the crashlog shows all the info).

After looking at the crashlog, the crash.dmp file in visual studio and debugging the code, it appears that the crash happens inside the functions SceneManager.LoadSceneAsync
or SceneManager.LoadScene (we tried both) when we call it to transition from one scene to another, in a windows build (64 bits) and it doesn't happen always or in a consistent way.

We are not sure what else we can try as a workaround or if there is any solution or we are missing something since the crash is quite random and it is still affecting our customers.

Thanks!

 

Hello, Sometimes we had similar crash

I also attached crash errors.

 

Hi,

some of our players are experiencing this too. The problems started after upgrading from 5.6.2p2 to 5.6.3f1. Builds using 5.6.2p2 were running just fine

Here is our crash log:

 

We move back to 5.6.3 look like this issue is only for 2017.

 

Apologies for bumping an old thread but I recently encountered this same problem. I am working on a project that is using VR and currently working with VRTK on unity 5.6.0f3. I can run the game fine on the editor but when I make a build and run the executable it crashes. By that I mean it goes through the Unity splash screen and then loads the first scene which works for a second and then freezes. Nothing is rendered on the headset. The architecture is set to X86_64 since I had a DllNotFoundException error message showing in the log when the it was set to X86. I've enabled the PDB which shows me the stack trace as opposed to giving me a SymGetSymFromAddr64 error, although I still quite understand what the issue is. Would appreciate it if someone could tell me what I should be looking at to fix the issue.

Someone earlier mentioned that the problem seemed to have fixed itself when they upgraded to 5.6.1. I'll try that now, although it's going to take a while with Unity converting the assets over.

edit: I would also like to mention that I have tried reimporting the Oculus utilities and avatar which doesn't seem to fix the problem

 

We have closely related issue as it gives stack trace like this:

There's a link to our topic:
https://forum.unity.com/threads/gra...ing-recently-logs-and-videos-included.501860/

My question is, could someone get any tips how to reat dump files from Unity? I guess any stacktrace would tell us anything since I have already lost about month of my worktime just by trying to prevent this crash.

 

There should be a checkbox within the build options, although it would have to be built for desktop. After checking that and running the executable, the next crash report would have something else other than SymGetSymFromAddr64.

 

@Ryanc_unity: I have a crash dump for you from 2017.1.0p4, and it's something that's been dogging one specific game of ours since 5.4. It's the same sort of thing with it seeming to be related to code in unity, and I have no idea what we're doing to trigger it.

A lot of times it's happening when switching between "rooms" inside our game (which is nothing but some mono objects moving around; no GameObjects, even); but these ones are during exit of the game or alt-tabbing out.

https://bugtracker.arcengames.com/view.php?id=19313

Any clues on what we can do would be much appreciated; it's been an absolute huge annoyance for our title with that happening for some people and us unable to figure out why.

edit: Also, another report from a different user: https://bugtracker.arcengames.com/view.php?id=19314

 

A but of a similar issue here: I use Unity 2017.3 and my build crashes when I close the application. Like others the only thing I see in the logs is "ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.'". The weird thing is that it only crashes if it is a development build without "Copy PDB files" ticked. If it is a Release build, no crash. If "Copy PDB files" is ticked, no crash. Attached one of the crash dumps generated.

 

The issue that I and others have been reporting is older than the experimental scripting runtime, though. There's something else going on, too.

 

Here's one crash dump that we have: https://bugtracker.arcengames.com/view.php?id=19313

I'm uncertain what to call another thread, since this could be anything, as you say. Any help on this would be greatly appreciated, as we're accumulating increasing numbers of these crash dumps in this one game.

 

Thank you Tautvydas-Zilys, I wasn't aware of the bug and will immediately upgrade to 2017.3.0p2

 

The game is configured to use DirectX9, or to go and use OpenGL if it can't use that.

The user reported that that crash was when alt-tabbing out.

These ones are from the same user, and were crashes on exit: https://bugtracker.arcengames.com/view.php?id=19314

Here's a crash with a dump when someone is just playing like normal (note that "changing a room" is not changing a scene in unity): https://bugtracker.arcengames.com/view.php?id=19386

Another one that is random that I don't know what caused it: https://bugtracker.arcengames.com/view.php?id=19381

Another recent one that happened during gameplay that also includes a video, since a youtuber was who ran across this during a play: https://bugtracker.arcengames.com/view.php?id=19347

Another recent crash moving between rooms: https://bugtracker.arcengames.com/view.php?id=19332

Recent crash not moving between rooms, but just killing enemies: https://bugtracker.arcengames.com/view.php?id=19324

Sudden crash during the tutorial recently: https://bugtracker.arcengames.com/view.php?id=19235

Much older crash when leaving a room: https://bugtracker.arcengames.com/view.php?id=18857
Another older crash when entering a boss room: https://bugtracker.arcengames.com/view.php?id=18908
Another somewhat old one: https://bugtracker.arcengames.com/view.php?id=18847
And another, which is old and doesn't have a crash dump file but does show a screenshot of what task manager did: https://bugtracker.arcengames.com/view.php?id=18925

I should note that for most people, we don't run into a lot of crashes, and most people run into none. This is also our only title out of about a dozen to have this sort of crash, so we're pretty flummoxed. It's really nice to be able to talk to someone who could potentially actually unravel this for us.

Cheers.

 

Fair! However, I have given bug reports in for this and a number of other issues, and there are some that have never even been looked at. We've been with you guys since 2010. There's one report that I made detailing how some simple math changes could make all unity games slightly faster for everyone, but that hasn't really gotten a look because of how it doesn't fit into the normal "follow these steps and a repro is found" pattern that your QA folks look for.

My experience has been that anything outside of that style of report gets ignored. I even tried getting paid hourly support (which was offered on the website at the time; I assume still is) back in 2011 or 2012, and never got a response. That was even back when I had a personal Unity rep, which isn't a thing anymore.

I've been hanging out in the forums for things like this because I've been able to actually talk to human beings rather than it just going into the void. I'm assuming that all of the above are a single issue that is being triggered in one way, and I'll go ahead and submit a bug report, but I thought you should know what the experience on that end has been like. I've had a couple of confirmed bugs that were closed, a few that are still open, a few that you guys fixed on your own which I later noted could be closed, and a lot that were ignored. Bare minimum, there's a lot of stale data in your bugtracker.

 

@Tautvydas-Zilys I've now tested 2017.3.0p2 and it looks like the issue is still there for me. It crashes again when I closed the application. Attached crash dump.

 

Got it. I really do appreciate that. The case number for the compound crash report that I've got is 995671.

Older cases by me that were resolved in past versions of Unity and can be closed now:
971715, 377260.

An open one that would take a senior engineer just poking around in the code some and getting some major gains on any substantially-sized unity game without any API changes: 918450. That one is filled with so-simple-it's-silly stuff, but in core classes in key bottlenecks I've observed, and so a little adds up to a lot.

Those are the main ones. There are three others that I have open, but one is on the long-term roadmap, and two others have been reproed and are somewhere in the bug queue.

Thanks again for taking a look.

 

Thanks again for the response @Tautvydas-Zilys I think I'll revert back to stable scripting runtime, looks like there are still too many things to fix with experimental. It was a nice-to-have for us anyhow, not a must

 

Someone got back to me for more info about 5 hours ago! Just figured I would post success in that part of the process.

 

If someone have solved this issue, please let me know

 

Will do. At the moment the best advice seems to be "make sure the graphics drivers are as up to date as possible." What version of Unity are you having the issue on, by the way, at the moment? Right now we're waiting on someone experiencing this with our windows build with pdbs on 2017.1.0p4.

If you're going to submit your own bug report, then they're going to want a build done with pdbs and with a crash dump generated with the version that had pdbs.
