I've identified potentially another issue with our application while running on iPad 3. The app crashes in a similar manner as when it crashes on iOS 6 and the iPhone 5. Unfortunately it is difficult to reproduce.

I can provide our project in its current state to reproduce the issue if you'd like.

The app throws a SIGSEGV on this thread on the iPad 3:

0 crime map 0x0046eb16 testflight_backtrace + 238
1 crime map 0x0046f800 TFSignalHandler + 264
2 libsystem_c.dylib 0x332557ec _sigtramp + 48

8 libdispatch.dylib 0x34984816 _dispatch_worker_thread2 + 258
9 libsystem_c.dylib 0x33206dfa _pthread_wqthread + 294
10 libsystem_c.dylib 0x33206ccf start_wqthread + 7

Here's the other stack trace on iPhone for reference.

I've memory profiled my application and removed several of the possible memory leaks that it identifies. However for the memory leaks in 3rd party libraries I have left those alone because I'm not sure they're legitimate.

Any help or direction you could provide would be great.
