Thanks for all the ideas.
I've seen many crashes in objc_msgSend. Every single one of them
was because
I had previously corrupted memory involved with a Cocoa object.
Now, the
method of corruption has varied across the whole spectrum of possible
mistakes. But generally, that's what you've got to focus on.
A side category which is kind of like memory corruption but slightly
different: the thing you're sending messages might not actually be a
real NSObject. This can happen either because you casted a non-
NSObject value, or because the object has already been released.
