    -----------------


    I'm sending all exceptions to online analytics to quickly fix bugs but sometimes il2cpp stack traces are useless and it's impossible to see what caused an issue or where it happened:
    Code (CSharp):
    1. public class TestButton: MonoBehaviour
    2. {
    3.     [SerializeField] Button button;
    4.  
    5.     private void Start()
    6.     {
    7.         button.onClick.AddListener( async () => await TestTask() );
    8.         //or button.onClick.AddListener( () => TestTask() );
    9.     }
    10.  
    11.     private async Task TestTask()
    12.     {
    13.         await Task.Yield();
    14.         throw new System.NullReferenceException();
    15.     }
    16.  
    17.     //or
    18.     //private async void Start()
    19.     //{
    20.     //    await Task.Yield();
    21.     //    throw new System.NullReferenceException();
    22.     //}
    23. }

    It also doesn't work correctly in Debug il2cpp mode.

    Can you submit a bug report for this issue? It looks like something that we should correct.

    That project is a bit messy but it seems like that's the reasons of missing stack trace.

    In clean project I get:

    A bit better, now I have TestButton.<Start> but still not as good as mono (TestButton+<TestTask>). Anyway once a bit more code is added to the project then that line is somehow replaced with something completely random:
    Code (CSharp):
    1.  
    2. NullReferenceException: Object reference not set to an instance of an object.

    Project that gives that error: https://drive.google.com/file/d/1L_4s7bbTEL0dBNQQ9_UaZXctKfoGtfMI/view?usp=sharing

    In my main project I get these kind of weird stack traces with tons of unrelated calls, for ex:
    Code (CSharp):
    1. IndexOutOfRangeException: Index was outside the bounds of the array.: MusicPlayer+<RaiseVolume>d__21.System.Collections.IEnumerator.Reset () (at <00000000000000000000000000000000>:0)
    2. BA.Game.UI.ResultController.SetResults (System.Int32 mapScore, System.Int32 maxCombo, System.Int32 totalScore, System.Single accuracy) (at <00000000000000000000000000000000>:0)
    3. TextCtrl+<DDAnim>d__5.System.Collections.IEnumerator.Reset () (at <00000000000000000000000000000000>:0)
    4. BA.Game.GameFlow.GameEnded (System.Boolean won) (at)
    These are 3 lines out of 30+ reported, MusicPlayer+<RaiseVolume>:
    Code (CSharp):
    1. IEnumerator RaiseVolume()
    2. {
    3.     while ( AudioListener.volume < volume )
    4.     {
    5.         AudioListener.volume += Time.deltaTime * 0.1f;
    6.         yield return null;
    7.     }
    8. }
    This bug couldn't even happen here :(

    Thanks for the bug report. It is certainly possible that stack traces with IL2CPP may be missing frames due to inlining. But there should not be any incorrect frames. We will investigate this.

    But this should not be the case in debug builds, right?

    Mono - fine
    Mono Development - fine
    Il2cpp - wrong
    Il2cpp Debug C++ compiler configuration - wrong
    Il2cpp Development - fine (Release or Debug C++ compiler configuration)

    Tried attaching 
    [MethodImpl( MethodImplOptions.NoInlining )]
    to code above and also to all methods and properties in all managed dlls using Cecil, il2cpp generated noinline but it didn't help. No idea, myb c++ async runner gets inlined?

    Il2cpp development build doesn't fix my problem, can't distribute that to players.

    Would it be somehow possible to force il2cpp development build behavior in normal il2cpp for specific methods or whole async/await logic?

    I'd like to know if this issue is possible to fix or not so I can start going back to mono or change as much as possible async/await to coroutines.

    I'm unsure why our QA team did not process this bug report yet. I've pinged them about it.

    It looks like our QA team started to process it, but then ran into an unrelated issue, and may have moved it to the back burner. I'll ping them again. Thanks for following up here.

    Just wanted to add a +1 here. We use Async/await and get really whacky call stacks on unity crash reports when viewing the stack trace

    I've finally had a chance to look into this issue. Thanks again for reporting it, these stack trace problems can be very specific to the code layout in a given project, and therefore difficult to reproduce.

    It turns out the problem is not specific to async/await workflows. More generally, IL2CPP is reporting incorrect stack frame entries for any instance methods on value types. Due to an implementation detail about how IL2CPP implements these methods, they were not being found properly by the stack trace creation code.

    I've been able to correct this issue, and it should be going out to patch releases in all active versions of Unity.

    @Kamyker: I'll ping you via the submitted bug report when the fix clears our testing and code review processes.

    Regarding line numbers in stack traces, it is on out list of things we would like to do, but we've not had the resources to complete it yet. I'm hoping that will change soon, but I cannot promise anything.

    I disagree you can always split a method to smaller parts to pinpoint an issue.


    The wait for 2020.2.5 begins.

    @JoshPeterson Thank you!

    I'm not sure it's a good idea, just a total overkill. If the feature was present in other backend, then it must be in the current one too.

    This should be corrected in 2020.3 as well. Any fixes in 2020.2 will also be in 2020.3.

    Then should I assume this stacktrace does not correspond to this issue? Seems quite similar.

    Code (CSharp):
    1. System.NullReferenceException: Object reference not set to an instance of an object.
    2.   Module "System.Runtime.ExceptionServices.ExceptionDispatchInfo", in Throw
    3.   Module "System.Threading.SendOrPostCallback", in Invoke
    4.   Module "UnityEngine.UnitySynchronizationContext+WorkRequest", in Invoke
    5.   Module "UnityEngine.UnitySynchronizationContext", in Exec
    6.  
    Im using Unity 2020.3.33 , IL2CPP iOS Builds

    If its not the case and this has nothing to do with the issue has someone some hint for me to find the issue? I'm aware there's a nullref somewhere in the code but without more info im lost. Btw I can't reproduce it has happened to some dozens of players.

    Thanks in advance

    It would not surprise me if this is a different stack trace issue. Where is that stack trace generated from? The word "Module" in is a bit odd - I don't think that normally shows up in C# stack traces.

    I think module is something Sentry adds, in normal stack traces I see the class and the method after 'Module'
    this is a normal stack trace received by Sentry too:

    Code (CSharp):
    1. System.NullReferenceException: Object reference not set to an instance of an object.
    2.   Module "PeopleLoader", in KillHuman
    3.   Module "HumanScripts", in KillPeopleInBuilding
    4.   Module "BuildingDataLoader", in RemoveBuilding
    5.   Module "BuildController", in BuildYes
    6.   Module "UnityEngine.Events.UnityAction", in Invoke
    7.   Module "UnityEngine.Events.UnityEvent", in Invoke
    8.   Module "UnityEngine.EventSystems.ExecuteEvents+EventFunction`1", in Invoke
    9.   Module "UnityEngine.EventSystems.ExecuteEvents", in Execute
    10.   Module "UnityEngine.InputSystem.UI.InputSystemUIInputModule", in ProcessPointerButton
    11.   Module "UnityEngine.InputSystem.UI.InputSystemUIInputModule", in ProcessPointer
    12.   Module "UnityEngine.InputSystem.UI.InputSystemUIInputModule", in Process
    As you can see this one tells all the info I need to pinpoint the source, but with the other one I have no way to know where the game is crashing

    You may want to check with Sentry to see if there is a way to get the "raw" call stack. They are definitely doing some post processing here. I wonder if that is related to the problem in the original case you mentioned.

    Woop woop!

    Will be very, very useful when getting logs from consoles, so we know where in the 
    #if UNITY_THECONSLE
    section the error is coming from :)
