Coincidentally enough, we've just hit a case where that's bad - it's a complicated situation with ObjC++ and C++ object lifetimes, resulting in an accessor that uses that pattern being called as a result of that object being in dealloc. By the time the autorelease pool pops the object it's trying to release is long gone. It's KVO unregistering, so there's not much we can do about it other than be smarter in our accessors.
