In this case, a backtrace isn't helpful at all: At the point where it
shows the signal delivery, the failure (most probably errors in
malloc/free handling or writing outside of allocated buffers) is only
detected, but it happened long before.

It would help a lot if you'd redo your test run, though not with gdb,
but using electric-fence. That will probably show where the actual bug
is hidden.
