Post crash debugging in Linux

- Enable core dump for your current session
chandra # ulimit -c unlimited

- Verify it is enabled
chandra # ulimit -c
unlimited

- Once you have a crash while running executable, check for core dump file.
chandra # ls -al core*
-rw——- 1 root root 50966528 Mar 26 14:57 core.7812

- Open your executable in kdbg. Then, import core dump file from File -> Core Dump.

You will see where the exe crashed and all memory and local variable goodies.
