How do you see that the self pointer points to code area?
I have added a retain in the init method of MapView (dirty hack)
- (id)initWithFrame:(NSRect)frameRect
{
NSLog(@"initWithFrame ...");
self = [super initWithFrame: frameRect];
[self retain];
...
}
to check your proposition and also did
- (void)dealloc
{
NSLog(@"MapView dealloc");
...
[super dealloc];
}
This changed nothing. The program still crashes at the same spot and MapView is
never deallocated (at least dealloc not called)!? And remember, the app works
perfectly well in two other environments (for whatever that's worth).

You mean
export NSZombieEnabled=YES
openapp <application>
?
Thanks,
Andreas
