Hi list,
My program puts some custom objects into a mutable set using [aSet addObject:anObject]; and when I inspect the set afterwards there are the objects I add and at least one instance of an NSCFTimer in there. I have no idea where that comes from; I'm not knowingly using NSTimers anywhere. Has anybody come across this strangeness with NSMutableSet at all?

It sounds like one of the objects you add to your set is prematurely deallocated due to one too many releases. So you have a dangling pointer reference. The deallocated memory gets filled with some other random object, in this case an NSCFTimer, and thereafter the pointer points to that object rather than your original one.
