====== How to Debug a segfault ======


  * To  debug segfaults enable core dumps:
<code bash>
ulimit -c unlimited
</code>

  * In the same console as you ran ulimit run whatever program segfaulted.
  * After it segfaults look for a core file
  * Then run [[wiki>GNU_Debugger]]:

<code bash>
gdb <prog_name> core
</code>

  * then run a stack backtrace in gdb

<code>
(gdb) bt
</code>

  * You should get a good idea about what caused the problem.
