I posted this to freebsd-questions, but though I would put it here also in case anyone has any ideas.
I am consistantly getting seg faults and bus errors when running a multi threaded python application under 5.3-release-p2. Python was built from the port(python 2.4) with threading enabled. Rebuilding with the huge stack size option enabled didn't make a difference. The application uses twisted (www.twistedmatrix.com) and it runs fine until I put it under a bit of a load and have 20-30 simultaneous threads running. Then it core dumps. Following is the backtrace from the core file. The backtrace is always the same. #0 0x2823cdbb in pthread_testcancel () from /usr/lib/libpthread.so.1 #1 0x28234b06 in pthread_mutexattr_init () from /usr/lib/libpthread.so.1 #2 0x00000000 in ??
