When a (UNIX) program exits abnormally it usally has received a signal
and probably has, depending on the signal (SIGSEGV, for example),
written a core dump.  You can then examine the core dump by running
gdb:

        $ gdb myapp core.1234

gdb usually jumps straight to the line where the crash occured.

If your program does not generate a core dump you can force it to do
so by calling abort().  A better solution is to provide an error
handler that automatically writes a core dump.
