I get the segmentation fault with NSZombieEnabled=NO as supposed.
But I get nothing with NSZombieEnabled=YES.
Is it a valid behavior?
The documentation states: ------------------------------------------------------------------------------------------------------------------------
Turning on zombies changes this behavior so that the isa pointer is modified to be that of the NSZombie class. When messages are
sent to the object, instead of crashing, ****NSZombie will use NSLog()**** to produce an error message. By default the memory used by the object
will not really be freed, so error messages will continue to be generated whenever a message is sent to the object, and the object
instance variables will remain available for examination by the debugger.
