One out of two times my app crashes and freezes at splash page

I'm still in development with my app and each time I "run" the app it crashes one out of two times. When it crashes the app freezes on the splash page and this is the error I get:

http://d.pr/i/rHjY

Could it be something to do with the splash page? It's just so odd that the app crashes one out of two times. Anyone got any idea?

My standart debugging workflow - If error origin is unknown - comment out everything in AppDelegate methods - mainly in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

and in these also, if You have anything there:

- (void)applicationWillResignActive:(UIApplication *)application

- (void)applicationDidEnterBackground:(UIApplication *)application

- (void)applicationWillEnterForeground:(UIApplication *)application

- (void)applicationDidBecomeActive:(UIApplication *)application

Then - if You don't encounter crashing anymore, then start uncommenting stuff. Once You find a code line (or code block) that crashes, then look deeper in that.

Good luck!

If you're using slightly older tools it might be related to this:

The issue occurs to a process race condition for debugserver. Instead of using GDB, you can alternatively kill your execution, wait a few seconds for the app to wrap up, and then run the next iteration.

The quick fix:

Update your scheme by selecting Product > Scheme > Edit Scheme, and choose the GDB debugger for your debug scheme.

But really you ought to just update your tools.

Add an exceptions breakpoint to see where in your code it is crashing: https://developer.apple.com/library/ios/recipes/xcode_help-breakpoint_navigator/articles/adding_an_exception_breakpoint.html
