Crash in UnityUpdateDisplayList (LibEntryPoint.mm:619)

Hi,

I'm hoping someone can help me figure out this iOS crash that is causing my app to get rejected by Apple. I'm not sure how to reproduce it so it's hard for me to debug it. This is Unity 2017.3.0f3.

Here is the symbolicated crash log:

Anyone have any clues? Thanks!

 

does it work in a local build to device?
how about in a test flight build?

and probably go search for similar recent issues if find something matching,
https://unity3d.com/search?refinement=issues&gq=iOS crash

 

I can't reproduce the crash myself yet (either with a local build or a test flight build). I searched through similar issues and haven't found a match yet. The best I can probably do is keep trying to reproduce it, but I'm hoping someone knows more about this particular class/method and can give me a clue as to what might cause a crash there. Otherwise I'm not even sure what part of my app to test. Or wait for Apple to respond to my question asking what they were testing when it crashed. Does anyone know if the source for those files (LibEntryPoint.mm, etc...) is available somewhere?

 

The same problem i met. Has it been settled?

 

I'm having the same problem on Unity 5.6.5. My app was rejected by Apple and the crash log shows the crash happens here:
UnityUpdateDisplayList (in Presidents) (LibEntryPoint.mm:578)

 

Hi ViggyMo ，Have you fix it？I met the same crash on Unity 5.6.4f1.I can't reproduce it too.

 

The same problem.
Unity 2017.2.0p2, Unity 2017.3.1f1

 

As a note, our app was rejected for the same reason. With some digging into issue tracker, we think it's https://issuetracker.unity3d.com/is...launching-app-from-url-with-airplay-connected. We've successfully repro'd the issue with iOS 11.2.6 with an unpatched Unity and regressed with 2017.3.0p2. Hope this helps!

 

For what it's worth, I installed the 5.6.5p2 patch and resubmitted my app to Apple and it was approved. I don't know if that actually fixed it or the initial rejection was just a fluke. Either way it works now...

 

same problem here - got rejected due to this crash, built with 5.6.3p2

will it ever be back ported?
