You are trying to get a backtrace inside a signal handler.  Unfortunately, 
backtrace() is not async-signal safe.

tcmalloc has a GetStackTrace function that was written to be async-signal safe 
-- you could try using that, though no promises (it wasn't really ever intended 
to be part of the public API).  It's processor-dependent, but should work well 
on i386, which it looks like is what you're using.
