Simple app crash on iPhone simulator/ Mac OS 10.8.4

Question

This morning, after updated the Mac OS on my Mac to 10.8.4, I wrote some code the Xcode 4.6.2 then pressing the Run button to compile. (You know, I don't have stop the simulator, just press the Run button to compile and run.). And boom, app crash :(, I try some others that're Ok on 10.8.3 but no luck, still crash. I found out some weird log in the Console.Do you know how to solve it?
