I'm frustrated with this problem. It's very weird, sometime when I run my iPhone app in Instrument Tool my app is crashed. But the thing is my app still can run normally in Debug/Run mode. And even worse, this happened in an inconsistent way, It's not crashed all the time, just sometime. I'm using XCode 3.2 (Snow Leopard), iPhoneSDK 3.1.2.
Does this happen to anyone?
