PhoenixFD for Maya crashes due to integer divide by zero error under mayapy

[vanpixelguy]

We're running PhoenixFD version 3.04.00 with the mayapy.exe from Maya 2016.5 on WIndows 7 x64 and encountering a crash. We enabled MAYA_DEBUG_ENABLE_CRASH_REPORTING and the crash is inside the PhoenixFD plug-in. Here is the information from the crash file generated when mayapy.exe terminates:

The simulation works interactively, just crashes when run from mayapy.exe which may be a red herring. What we're trying to do is drive the vertices of a polyhedral mesh from a PhoenixFD simulation. I am attaching the entire MayaCrashLog with the stack trace Note that the first 10 stack frames are missing (whatever phoenixfd is calling into).

Has anyone reported a crash like this?
Thanks,

Hey,

I think this one might not be in our bugtracker yet - would it be possible to send over the scene that exhibits the issue?

Thanks!

Hello. I'm still trying to isolate this into a standalone case which is independent of our pipeline. I'll work on this today. Thanks.

[Svetlin.Nikolov]

Thank you! Please ping us whenever you have something.

I'm attaching an example. Unfortunately its a script you'll need to run in a WiIndows shell window because the crash only occurs in mayapy mode, not interactively. Please let me know if you need help reproducing. Thanks.

Sweet! Thanks a ton! Got the crash and the fix will be in tomorrow's nightly.

Cheers!

Thank you so very much for the prompt turnaround! This really helps our production. Take care.
