Yes, can confirm the crash. Not quite sure whether this is related to FBX addon, or changes in mesh cache system, have to investigate a bit more.

I can't reproduce the crash on neither linux nor windows 7. Clang's asan and valgrind doesn't show bad memory access either.

Any devs around who can reproduce the crash?

So afaik it's trying to use freed cache data when rebuilding DM in update() func…

Might be something done wrong in FBX code too, have to try to find where this happens in py code.
