    We do have a few similar reports in our bug database, all for Unity version 2020.3 or earlier. Unfortunately we've not tracked down the cause of any of them.

    We have recently fixed a GC issue that is likely unrelated, but could be involved. If possible, please try the next Unity 2020.3 patch release. I'd be curious to know if that decreases the crash frequency you see with this call stack.

    You are talking about 2020.3.34f1? We will definitely try it, once it is released.

    I also found a bug report for the Boehm GC (Mono) that has a very similar stack trace: https://bugzilla.xamarin.com/21/21939/bug.html (unfortunately it was never resolved) - but maybe this helps track the problem down, as the user in the bug report talks about a potential fix.

    Looking at the bug status, I think you will need to wait until 2020.3.35 for the fix to be released. Unfortunately the bug report that looks similar is not public, so I don't have a public link you can track.

    It does sound very similar to that Mono bug report though, so this might be a promising avenue.

    I don't see any clear indication of this bugfix on the .35 release notes, could you confirm if is there?

    We have released a new version with unity .35 and are still seeing this problem. So it does not seem to been fixed

    @sdg_unity @YVR_Unity

    The changes on our end that corrected the internally discovered issue are in Unity version 2020.3.35, so I suspect that there is some other cause of this problem.

    Can one or both of you submit bug reports for this issue? Often these problems require some deep debugging, so having a project that reproduces this in invaluable.

    Does this happen in the Unity editor, or in a Unity player? And does this happen only with incremental GC is enabled?

    This happen in Unity Editor when BuildPipeline::CompilePlayerScripts is invoked. This problem occurs occasionally.

    Incremental GC is enabled in Build Player Setting. But I think this option only affect the final application.

    Thanks for the details, can you submit a bug report for this? This is the kind of thing that we need to debug deeply.

    Hi,
    Have encountered same issue. Using unity 2020.3.35. Incremental GC is disabled.

    The game crashing very often. It is multiplayer, so it's crashing on multiple clients at the same time. Here is stack trace:

    I don't think that we ever had a bug report for this issue. Can you submit one?

    Hi, I would like to report it, but the problem is that I still can't isolate the problem or get the precise pattern of it's appearing.
    Yesterday I've moved to 2020.3.38. Today we did some tests and the issue is still exists.

    The only thing I can say for sure, it mostly happens when something is "exploded" (allocated) during the game. But the pattern of this issue is unpredictable. It happen on both clients simultaneously, or might be only on one client.
    I did external tests with debug "explosion" button to spam explosions over the map. It may take over couple hundred explosions with no issue, but next time just few with exactly same crash for both clients.

    Thanks for checking on this! I don't have a good sense yet about what the cause is from these call stacks alone. Please report any additional information you find here though. Every little bit of data will help us eventually track down the root cause.

    Sure, I'll keep looking for a reason as it's high priority atm. Maybe even have to try it on previous versions of engine. The project is already third year in development, and there wasn't any issue before. Ill be right back after I have more details.

    Ok, the issue was finally isolated. As I said it was on explosion during memory allocation. There is a method that modifying the terrain. You may try it yourself by putting this into infinity loop.
    Code (CSharp):
    1.  
    2.  
    3. private TerrainData GetTerrainData() => _targetTerrain.terrainData;
    4. private Vector3 GetTerrainSize() => GetTerrainData().size;
    5.  
    6. public Vector3 WorldToTerrainPosition(Vector3 worldPosition)
    7.     {
    8.         var terrainPosition = worldPosition - _targetTerrain.GetPosition();
    9.  
    10.         var terrainSize = GetTerrainSize();
    11.  
    12.         var heightmapResolution = GetHeightmapResolution();
    13.  
    14.         terrainPosition = new Vector3(terrainPosition.x / terrainSize.x, terrainPosition.y / terrainSize.y, terrainPosition.z / terrainSize.z);
    15.  
    16.         return new Vector3(terrainPosition.x * heightmapResolution, 0, terrainPosition.z * heightmapResolution);
    17.     }
    18.  
    19.     public Vector2Int GetBrushPosition(Vector3 worldPosition, int brushWidth, int brushHeight)
    20.     {
    21.         var terrainPosition = WorldToTerrainPosition(worldPosition);
    22.  
    23.         var heightmapResolution = GetHeightmapResolution();
    24.  
    25.         return new Vector2Int((int)Mathf.Clamp(terrainPosition.x - brushWidth / 2.0f, 0.0f, heightmapResolution), (int)Mathf.Clamp(terrainPosition.z - brushHeight / 2.0f, 0.0f, heightmapResolution));
    26.     }
    27.  
    28.     public Vector2Int GetSafeBrushSize(int brushX, int brushY, int brushWidth, int brushHeight)
    29.     {
    30.         var heightmapResolution = GetHeightmapResolution();
    31.  
    32.         while (heightmapResolution - (brushX + brushWidth) < 0) brushWidth--;
    33.  
    34.         while (heightmapResolution - (brushY + brushHeight) < 0) brushHeight--;
    35.  
    36.         return new Vector2Int(brushWidth, brushHeight);
    37.     }
    38.  
    39. public void LowerTerrain(Vector3 worldPosition, float strength, int brushWidth, int brushHeight)
    40.     {
    41.         var brushPosition = GetBrushPosition(worldPosition, brushWidth, brushHeight);
    42.  
    43.         var brushSize = GetSafeBrushSize(brushPosition.x, brushPosition.y, brushWidth, brushHeight);
    44.  
    45.         var tempHeights = GetTerrainData().GetHeights(brushPosition.x, brushPosition.y, brushSize.x, brushSize.y);
    46.         var tempDetails = GetTerrainData().GetDetailLayer(brushPosition.x, brushPosition.y, brushSize.x, brushSize.y, 0);
    47.  
    48.         for (var y = 0; y < brushSize.y; y++)
    49.         {
    50.             for (var x = 0; x < brushSize.x; x++)
    51.             {
    52.                 tempHeights[y, x] -= strength * Time.fixedDeltaTime;

    The engine does silent crash at some point if "LowerTerrain" function are repeatedly invoking.

    So any solution for this GC problem? or any way to get around it ?

    I don't recall if we ever had a bug report on this issue. @jjxtra can you report one so that we can investigate?

    I constantly get "Fatal error in GC" "Unexpected mark stack overflow" in a IL2CPP server build with a high amount of GameObjects and colliders. Minimal reproduction project with 100% reproduction rate is attached to IN-64035.
    Incremental on/off doesn't make a difference. Mono seems to work fine, only IL2CPP is affected.

    After reading through this thread, this might be the issue. The usecase for us is a persistent game server with a fairly big static game world, always crashing with the GC error at startup when trying to load the world. With a smaller world or with Mono backend it's still working fine.

    Seeing a very similar "Fatal error in GC" crash with 30+ gameObjects with colliders all being interacted with via some Physics.OverlapShere calls, probably 4-5 calls per second on each of those game objects. Mono does not crash, but IL2CPP is blowing up maybe 1 in 30-40 play throughts with high densities of enemies being interacted with.

    Is there anything reproducible here that we could look at in a bug report? This feels like something we will need to investigate for a while to pin down the cause.

    Not really, my tester has only seen the crash twice in about 90 sessions and since its only in the IL2CPP standalone builds, it makes it near impossible to see what's going on. The player.log also didn't have anything of use either. Is there any extra logging that can be enabled for il2cpp builds to help provide some more info?

    No, I don't think there is anything built in that will help with this, sorry!

    We encountered a similar issue as our application also crashes with an "Unexpected mark stack overflow" exception so I thought I report it here since this thread was recently active. Our application exists for years now and this is the first time we came across this issue.
    We use a Windows 64 build using Mono and .NET. We tested using latest Unity LTS 2022.3.20f1 and 2023.2.12f1 with the same result. We didn't test with the latest beta yet. The crash happens in a time frame from a few hours to up to 24 hours. When we disable 'Incremental GC' the application runs for days. So we are pretty positive that this is what causes the crash. But of course we don't want to have to disable the incremental GC feature. We also found out that the problem seems to be related to part of our application that runs a thread to receive audio via a C++ plugin. If we don't run this thread the application also runs for days. But there is no obvious culprit there and as mentioned it also doesn't crash with incremental GC disabled. We already tried lots of different approaches on the audio thread and got rid of any unnecessary allocations. The crash logs show that the crash always happens at different parts of the application but the last lines of the stack trace are always the same:
    Code (CSharp):
    1. 0x00007FFD39ED14F6 (mono-2.0-bdwgc) mono_breakpoint_clean_code
    2. 0x00007FFD39C4F35B (mono-2.0-bdwgc) mono_gc_register_root

    14. 0x0000016599852A2E (Mono JIT Code) (wrapper managed-to-native) object:__icall_wrapper_ves_icall_array_new_specific (intptr,int)
    Does this look familiar/are there comparable issues or should be create a new bug report? It will be hard though to create a project for recreating the issue. I attached a few more complete stack traces in a file and here is also the code from our audio receiving thread:

    Code (CSharp):
    1. private void AudioCaptureLoop()
    2.         {
    3.             while (!exitThread && NdiReceiver != IntPtr.Zero)
    4.             {
    5.                 var receivedFrameType = NDIlib.recv_capture_v2(NdiReceiver, null, ref receivedAudioFrame, null, 1000);
    6.  
    7.                 if (exitThread || receivedFrameType != NDIlib.frame_type_e.frame_type_audio ||
    8.                     volume == 0 || receivedAudioFrame.p_data == IntPtr.Zero || receivedAudioFrame.no_samples == 0)
    9.                 {
    10.                     NDIlib.recv_free_audio_v2(NdiReceiver, ref receivedAudioFrame);
    11.                     continue;
    12.                 }
    13.  
    14.                 if (!exitThread)
    15.                 {
    16.                     lock (audioLock)
    17.                     {
    18.                         ConfigureAudioOutput(receivedAudioFrame);
    19.                         if (!exitThread && AudioOutputInitialized)
    20.                             PlayReceivedAudio();
    21.                     }
    22.                 }
    23.  
    24.                 NDIlib.recv_free_audio_v2(NdiReceiver, ref receivedAudioFrame);
    25.             }
    26.          
    27.             Log.Trace($"Stopped audio capture for NDI stream '{NdiSource.SourceName}'");
    28.         }
    29.  
    30.         /// <summary>
    31.         /// Convert the received audio data to the required format and add to output buffer.
    32.         /// </summary>
    33.         private void PlayReceivedAudio()
    34.         {
    35.             // CSCore is expecting interleaved audio but NDI uses planar
    36.             interleavedFrame.sample_rate = receivedAudioFrame.sample_rate;
    37.             interleavedFrame.no_channels = receivedAudioFrame.no_channels;
    38.             interleavedFrame.no_samples = receivedAudioFrame.no_samples;
    39.             interleavedFrame.timecode = receivedAudioFrame.timecode;
    40.  
    41.             // We're working in bytes, so take the size of a 32 bit sample (float) into account
    42.             var bufferSize = receivedAudioFrame.no_samples * receivedAudioFrame.no_channels * sizeof(float);
    43.             var audioBuffer = GetOrCreateAudioBuffer(bufferSize);
    44.      
    45.             interleavedFrame.p_data = audioBuffer.Pointer;
    46.             NDIlib.util_audio_to_interleaved_32f_v2(ref receivedAudioFrame, ref interleavedFrame);
    47.             bufferingSource.Write(audioBuffer.Buffer, 0, audioBuffer.Buffer.Length);
    48.         }

    Thanks for the information! I'm going to guess that the symbolication of the call stack in the Mono native code is not correct. These methods are only called when the script debugging option is enabled. To confirm - are you seeing this when script debugging is disabled?

    In this case, I would look closely at the memory behavior of the C++ code in the audio plugin. Without seeing that code, I would guess that it corrupting some managed memory. That kind of thing can be exposed by incremental GC, as the incremental mode is pretty strict about requiring write barriers when managed objects are changed.

    To be clear, if the native code is behaving correctly, then it should work find with incremental GC, but since there are crashes happening, I would look closely at that code first. We've seen similar issues like this before.

    Thanks for your quick reply! We actually don't have script debugging or any other development option enabled in our build settings for these tests. Unfortunately the C++ code is Vizrt's SDK for receiving NDI streams and is closed source.
    In the meantime we ran the application with the latest Unity beta which also crashed after a few hours. We're also currently running a test where we commented out everything but the parts accessing the C++ SDK which seems to run fine for about 2 days now. Something we also tried was using NativeArrays for the audio data and passing its pointer to the C++ plugin. But that didn't change anything. If you have any other information/ideas for what we could try we would be very thankful.

    Thanks for the additional details!

    So it does look like the Mono stack frames are not correct then, since you don't have script debugging enabled. The lack of correct stack frames might make tracking down the cause more difficult.

    I would still focus on that C++ plugin. Can you put it into a standalone .NET Framework executable? I'd be curious to know if it causes problems outside of Unity. That might help us indicate if the issue is with that library or with the Mono p/invoke implementation.
