C'mon, you are going to have to do more work to figure out what's going 
wrong.  Posting a stack is not nearly enough.

It looks like your build lacks debugging information that could point to 
the line number at which the crash occurred.  You'll want to fix that. 
Then you can dump registers and memory relevant to the crashing 
instruction and what led up to it.

You should dump all threads' stacks to see what else was going on.
