iOS 7 Application Crashing the whole iPad

I am getting a very strange crash while using an application in iOS7. It's basically an eReader application that I am working on and while opening a book, and putting iPad to sleep, the whole iPad crashes!!! It just doesn't crash, it freezes completely and the user will have to hard reset it by pressing and holding the home and lock button. If they don't, the iPad will restart in 5 minutes but for that period, the iPad is completely frozen.

I have spent numerous hours and checked to see if all the threads are clean, tried deleting all the application delegate methods like "applicationWillResignActive", "applicationDidEnterBackground" etc but no go!

I am adding the log of the console:

As you can see in the line: Oct 21 13:55:58 iPad com.apple.launchd[1] (UIKitApplication:com.lightsail.ereader[0x9a12][173]) : (UIKitApplication:com.lightsail.ereader[0x9a12]) Exit timeout elapsed (1 seconds). Killing

It says something about exit timeout. com.lightsail.ereader is the identifier of my application.

Never mind. It was a C++ file trying to access the device partitions that crashed the iPad. I managed to fix the problem by deleting that code. If anyone else is facing the same problem then I recommend that they check the file operations in their code to isolate the problem.
