Bug / Crash ClearTasks / GetPointCloudAnisotropy

[yoke_sune]

Hey Sune,

I'm seeing this also (2018.4.2f1) - For me this happens when spawning a prefab with a solver via the editor.

ObiArbiter appears to be the culprit...

Glad to hear that i'm not completely lost, but also unfortunate you're facing the same issue.

Are you using multiple solvers?

I also spawn a GameObject, and i figured it was because of this. The weird thing is that i have it running on another larger PC where it does not crash. This pc has an i7 8700k and it seems to crash more frequently on a NUC with a i7 8809g with fewer cores (6 vs 4).

I can't really get a proper stack trace since i do not have the pdb for libOni. I cannot attach the crash dump here for some reason, but let me know and i'll gladly send it.
