Bug ECS Crash in android. UnityEditor:2021.3.8f1; ECS+NetCode:0.51.1-preview.21;il2cpp

At the end of the battle, I call the dispose method of the client ECS World in the LateUpdate of MonoBehavior.

Code (CSharp):

1. private void LateUpdate()
2. {
3.     _commandInTick.Clear();
4.     if (_destroyECSFlag)
5.     {
6.         var clearWorlds = new List<World>();
7.         foreach (var world in World.All)
8.         {
9.             if (world.GetExistingSystem<ClientSimulationSystemGroup>() != null)
10.             {
11.                 clearWorlds.Add(world);
12.             }
13.         }
14.         foreach (var world in clearWorlds)
15.         {
16.             world.Dispose();
17.         }
18.         _instance = null;
19.         _destroyECSFlag = false;
20.     }
21. }

Application crash when calling world.Dispose.The crash log is in the attachment tombstone_02.
I tried to restore the stack with ida and il2cppdumper.

Code (CSharp):

1. ChunkDataUtility.DeallocateBuffers
2. EntityComponentStore.Destroy(EntityComponentStore* entityComponentStore)
3. EntityDataAccess.Dispose
4. EntityManager.DestroyInstance
5. WorldUnmanaged.Dispose
6. World.Dispose

This problem only occurs in il2cpp. Mono will not crash

 

Did you find a solution to this problem?

 

me too!
