title: Xcode App Crashes with error randomly
body: <p>I'm making an iPhone app in objective c and have run in to an issue. Every 15 or so runs, it throws a random error saying "libc++abi.dylib: terminate called throwing an exception". I can't track down which code is causing this, as it's random and not very often. I've run the zombie profiler on it and there are no zombies. I'm using ARC. Can anybody offer any advice for finding the cause of this?</p>
  
  <p>Thanks</p>
