ok. that's because Ubuntu is not (by default) setup for
developers.
But you can enable core dump for your executable easily enough.
e.g, if you out file is a.out, then do this:
ulimit -S -c unlimited a.out
(now run your program, and you'll get core file in the same dir
where the program is)
(this won't be remembered after a reboot, so just do it when/as
required).
You can view the core file using > objdump -s core
Good luck understanding the contents of that ;-)
Core dumps typically require some specialised expertise to
analyse.
Unless you're one of those specialists, then better to just run
your a.out through the debugger, and forget about the core dump
(until you can't) ;-)
