Crash on StackAllocator::WalkAllocations when there's a memory leak in Play mode
Reproduction steps:
1. Import the attached .unitypackage to a project ("CrashScene.unitypackage")
2. Open Scene "200%"
3. Enter Play mode
Reproducible with: 2019.3.0a7, 2019.3.6f1
Not reproducible with: 2017.4.38f1, 2018.4.19f1, 2019.3.0a6, 2020.1.0b2, 2020.2.0a3
First lines of the stacktrace:
0x00007FF7773DB8A0 (Unity) StackAllocator::WalkAllocations
0x00007FF7773E8DF6 (Unity) TLSAllocator::WalkAllocations

0x00007FF777CD6388 (Unity) ExecutePlayerLoop
0x00007FF777CD645D (Unity) ExecutePlayerLoop
Note:
- The crash seems to be caused by a memory leak, which in turn when aggressively allocating, often bumps into a SIGSEGV error.
