When running on Tiger, my NSWindowController subclass that runs a modal
preferences dialog gets a retain message after it has been deallocated.
I can't reproduce this on Snow Leopard. The backtrace starts:
#0 0x92cc5fb8 in -[_NSZombie retain] ()
#1 0x92c2f1cc in -[NSInvocation retainArguments] ()
#2 0x93c5bc70 in _NSSendCommitEditingSelector ()
#3 0x93c7f1ec in -[NSController
_controllerEditor:didCommit:contextInfo:] ()
#4 0x90a461f4 in objc_msgSendv ()
#5 0x92bf3fcc in -[NSInvocation invoke] ()
#6 0x92bf457c in -[NSInvocation invokeWithTarget:] ()
#7 0x92c02f38 in __NSFireDelayedPerform ()
#8 0x907f2384 in __CFRunLoopDoTimer ()
Items #2 and #3 make me think this might have something to do with the
NSEditor protocol, but I don't understand how. As far as I can tell, I
don't have any objects that conform to that protocol... no NSDocument,
no NSObjectController, etc.
I saw a release note saying that in 10.5, NSWindowController was changed
to send setNextResponder: nil to its window on dealloc, to prevent
zombie messaging, so I tried that, but no joy.
