[WebGL] [Unity Physics] JobTempAlloc warnings and Memory access violation errors are thrown when entities are colliding
Reproduction steps:
1. Open the attached project ("case_1267503-WebGL-ECS-crash.zip")
2. Switch build target to WebGL
3. Build and run the project
4. Open browser's console and inspect the logs
Expected result: No warnings/errors are thrown
Actual result: JobTempAlloc warnings are thrown each time sphere collides with the plane, and after a while "Memory access violation" error is thrown and build crashes
Reproducible with: 2019.4.8f1, 2020.1.2f1, 2020.2.0a20
Couldn't test with: 2018.4 (ECS is not supported)
Tested with package(Unity Physics) versions: 0.4.0-preview.5, 0.4.1-preview
Notes:
1. The issue does not reproduce in Editor, or Windows Standalone (Mono) builds
2. IL2CPP build crashes on launch because of missing imports
-
Resolution Note (2020.2.X):
An issue with the job system related to single threaded platforms was causing this crash, and has been resolved.
