Sculpt crash on OS X with OpenMP
Closed, ArchivedPublic

Description

A sculpting crash was reported on BA, appears to be OpenMP related:
http://blenderartists.org/forum/showthread.php?251449-Is-sculpting-in-recent-trunk-(with-BMesh)-very-buggy&p=2092726#post2092726

I wasn't able to reproduce it on Linux, was hoping someone can test this on OS X, or comment if there are known issues with OpenMP there?

The file from that thread is attached, steps to reproduce is just enter sculpt mode and start drawing strokes.

It's a known bug in the apple gcc compiler which we can't fix. For official releases we use a newer gcc version which solves the issue, but if you're compiling with a standard compiler as part of Xcode you should just disable OpenMP (which is the default).
