Anybody knows what this crash report means - Cloth and Softbodies?

For some reason fluid softbody and armatures seem to crash on OS X a lot, even with simple scenes.

Often the few first frames work and then it crashes.

Here is a video of what happens:

Here is a video which also shows that the mesh disappears when I go into edit mode.
The cache can easily be corrupted but a free cache command does not reset it and Blender does not recalculate it.

Hi
HereĀ“s a testbuild that uses newer gcc-4.6.1 with omp 3.1.
This fixes all omp related bugs for OSX

Jens thank you very much for this help.
I could not do this at all.
