推荐答案
作为对Ian说的补充：
将环境变量NSZombieEnabled设置为YES
As a complement to what Ian says above: set the Environment variable "NSZombieEnabled" to YES and you will hopefully have a more informative fail.
（在XCode 4中，环境变量位于编辑方案下，选择调试）
(In XCode 4 the Environment Variables is found under "Edit Scheme" and select "Debug")
