I got the crashes too with that file (takes
about 70-90 frames here).

Valgrind was giving me some inconsistent info,
so I start to play with the optimization levels.
I find that if I set the optimization for linux
to -O0 and then touch threads.c and all the stuff
in render/intern/source, then type "make", blender
no longer crashes. At -O1 it still crashes.
