As was discussed on the objc-language list recently, the ARC spec specifically 
guarantees that an object's lifetime includes the entire duration of a method 
invocation. An object *cannot* be deallocated while one of its methods is 
executing.

Britt, have you tried upgrading your tools? Xcode 4.1.1 is pretty old in terms 
of ARC bugfixes. This might be a codegen issue.
