I'm facing a similar problem right now - I'm getting an EXC_BAD_ACCESS
exception in my app at semi-random times.

I tried setting NSZombieEnabled, (double clicked on my executable in
the XCode Groups & Files list and added NSZombieEnabled as an
environment variable set to yes) but I'm not seeing any additional
messages logged anywhere that I can see.  Nothing in the GDB console,
the system console, or anywhere I can think of.  Is there some magic
place that Zombie messages should be appearing?

Right now I can only make guesses as to exactly what's going on.  The
logical route I have right now to working out what could be causing
this is to insert a whole big stack of debug logging.  Any other
suggestions would most definitely be appreciated.
