You mean something like "Exiting due to SIGSEGV"?  That's caused by
trying to access memory you don't own.  Overrun, corrupted or NULL
pointers, usually.  FAQ section 9.2 explains some ways to find the bug.

Are you sure you didn't somehow manage to execute that code twice?

It's also possible that secondary damage from whatever bug caused the
above crash (or another one) messed up the program's state.  If you
can't reproduce it, there's probably not much anyone can do about it.
