Yes, that is the thing that I don't under stand either.

One assumption offered earlier was stack corruption. I translated that
into probably using some already freed/release object. For that
assumption the crash occurs very predictably, though. Also I tried to
set NSZombiesEnabled=YES, and that didn't change anything.

What are other causes of stack corruption?
