To dredge up some old stuff I found in the mamasam archives:

Is this stiff the case? I'm having autorelease errors with some of my
code that uses NSArrays of NSNumbers, and Zombies aren't breaking
before I get EXC_BAD_ACCESS, so I'm guessing yes.

Interestingly, if I run the program, I get a message:
   _NSAutoreleaseFreedObject(): release of previously deallocated object
(0x1adb810) ignored
But this does not appear when I'm debugging.

If it is, how do I go about finding what in the world the object is
that's being messages while dead? The only thing I can think of is to
create a wrapper class that passes all messages to the wrapped
NSNumber, making sure that all other functionality still works. But
that doesn't sound like a heck of a lot of fun any ideas?
