Summary: Segmentation fault when application finishes
Original Submission: Some applications generate a segmentation fault when
finishing.
It goes like this:
NSApplication -dealloc releases the GSDisplayServer associated
to _app_icon_window. It gets deallocated.
NSResponder (NSApplication's super) -dealloc releases _menu
menu releases it's window.
NSWindow's dealloc calls GSServerForWindow(self) and obtains a pointer to the
deallocated server.
NSWindow sends removeDragTypes:fromWindow to this deallocated object... boom!
The problem is that there is a NSMapTable to map windows to
DisplayServers, and this map doesn't get updated when a displayserver is
deallocated.
Adding the following method to GSDisplayServer and calling it from -dealloc
solves the problem.

- (void) _removeFromWindowMap
{
NSMapEnumerator enumerator;
void *key;
void *val;
enumerator = NSEnumerateMapTable(windowmaps);
while (NSNextMapEnumeratorPair(&enumerator, &key, &val))
{
if (val == self)
{
NSMapRemove(windowmaps, key);
}
}
NSEndMapTableEnumeration(&enumerator);
}
