Crash out of physx::PxsBroadPhaseContextSap::batchUpdate

Unity Engine
1

I’ve submitted this as a bug already (case 878740), but am posting here as well in case anyone has ideas or workarounds.

We’re seeing a “random” crash during gameplay that we’ve narrowed down to being apparently PhysX related. The stacktrace appears as something like:

========== OUTPUTING STACK TRACE ==================

0x0000000141ECF27F (Unity) physx::PxsBroadPhaseContextSap::batchUpdate

========== END OF STACKTRACE ===========

By process of elimination, I’ve created a reproduction case that involves rapidly creating/destroying certain objects. However, I haven’t yet been able to determine what is different about the objects that crash more frequently vs those that don’t.

EDIT: so far I’ve reproduced this on 5.5.0p4 and 5.5.1f1

Hei Midgardsormr,
did you find a solution for this crash meanwhile? I fight with the same Error. Tought first the Crash depends on my Scripts but figured out now, that the three NullRefs from my Script aren’t responsible for them. …
