This is the symbol that GCC uses for the list of selectors in a module.  It 
should never appear on the stack.  The SegV is probably triggered because the 
loader will want to map this part of the binary without execute permissions.  
The runtime has probably been passed an invalid pointer and returned a nonsense 
IMP, so, as Fred says, this is most likely to be caused by sending a message to 
a released object.

Either NSZombieEnabled=YES or valgrind should help you pinpoint the error.
