I occasionally get difficult-to-debug crashes where that last thing in
the crash log is a message being sent, which ends up being a message
sent to an object that has been released (I think it is objc_msg, but
I am not looking at a crash log now). These happen much more often in
Leopard than in Tiger.
Since I have many messages going to many objects, it can take me a
long time to track these problems down (in one case several weeks). I
am fairly certain it is not a notification message because I also
remove objects as observers before they are deallocated. Is there a
debugging tool that can provide more information about what message
was sent to what object at the time of the crash?
