System Information
Win 7 x64

Blender Version
Broken: 26b2323189

Short description of error
Files with some modifiers (mostly boolean) often crash randomly. Mostly at render start or render end, but also during modeling.

Exact steps for others to reproduce the error
It's very random, simplifying the file make it work properly apparently, so here is a trace:

Please provide a blend-file which can reproduce the error.

Campbell Barton changed title from ~~random crash with modifiers~~ to random crash with bmesh boolean modifiers

managed to get a reproducible case. But I get the feeling it's only one of many bugs. Will see, here is the file: crash bool3.blend
