Run your program under gdb. When GDB stops with the intentional
SIGSEGV or SIGABRT, do "sig SIGSEGV" or "sig SIGABRT", which should
continue the program into the sigal handler, into obtain_backtrace and
into libunwind, and then GDB should stop with another crash. At that
point you'll know where this is crashing, and perhaps why. Use the
usual debugging techniques if the reason for the crash is not obvious.
