Crash on PhysicsScene::ProcessTriggerEnterExits when splitting meshes that also exit a Trigger with OnTriggerExit
How to reproduce:
1. Open attached project
2. Open CrashDemo Scene
3. Enter the Play Mode
Reproducible with: 2018.3.0a6, 2018.4.1f1, 2019.1.3f1, 2019.2.0b2, 2019.3.0a3
Not reproducible with: 2017.4.27f1, 2018.3.0a5
Actual results: crash
Fixed in: 2020.1.0a7
WORKAROUND: The crash happens if a MeshCollider that is currently overlapping with another collider, gets its mesh set to null and then destroyed. Don't reset the sharedMesh to null before destroying meshes that are in the state of overlapping with other objects.

This is also preventing us from shipping. Hoping this will be fixed soon.

We were also experiencing a similar bug crash with the same stack trace. In our case however, it was in relation to calling AddComponent<RigidBody> on an object with a MeshCollider not marked Convex. This object would then interact with another trigger in the scene and cause a hard crash in both editor and on device.

Thank you for discovering the workaround! I upgraded from 5.6 and was facing this crash.
