I really have no idea about how to debug this. Should i suspect a crash in a library called by my app ? Am i responsible for this crash, where to look at then ? Of course the line 14 in Killer main is:

int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");

thank you very much guys

The crash log gives very little information. Anyway, I am puzzled by that:

objc_exception_rethrow
__cxa_rethrow

so it seems that there is some C++ exception handling going on. (Specifically, while handling an exception, another exception is thrown. This will cause terminate to be executed).

This might give you a hint. Are you using any C++ library?

You could also try and set NSSetUncaughtExceptionHandler but I suspect you are not able to reproduce the issue...

(Of course, it could well be some iOS SDK framework written in C++ to cause the exception, but just to check)...
