System Information
Operating system: Darwin-18.7.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon R9 M370X OpenGL Engine ATI Technologies Inc. 4.1 ATI-2.11.20

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449
Worked: (optional)

Short description of error
The scene is pretty simple, a house with some elements used as rigid bodies and some force field, vortex and wind force are applied.

When I play the animation, it starts and around frame 140-200 it crashes.

Exact steps for others to reproduce the error
Attached blend file. The only thing to do is to play the animation and wait for the crash.
Attached crash report.Blender_2019-08-26-215345_MacBook-Pro-de-Kote.crash

here test file work fine on linux Blender 2.80 f6cb5f5449 (Stable) AMD FX8350, 16GB DDR3, GTX690 2+2 GB VRam- Nvidia drivers 435.17, with Factory Setting applied, LoadUI enabled and Trusted Source disabled in file browser

i wait for 15-20 animation loop, no crash

I tested it also on Blender 2.81 and I have the same crash.

Could it be related to the OS? I will try with a windows environment tomorrow, to see if it works there.

Can confirm, crashes in bullet because there are NaNs in a specific vector seperatingAxisInA.
Would need some further investigation, will confirm for now...

backtrace (localDirOrg has NaNs here -- due to NaNs mentioned above...)
