title: Strange crash when presenting view controller
body: <p>I get a strange crash when presenting a modal view controller on iOS 7, it only happens on iPhone 5C I haven't been able to repro on the iPhone 5 or 5s. I've attached the crash log below, as well as the code that presents the view controller.  I used the presenting view controller as the transitioning delegate to have a custom fade in effect.  Please let me know if you need any more information about this.</p>
  
  <p>Code to present:</p>
  
  <pre><code>PresentedViewController *vc = [[PresentedViewController alloc] init];
  vc.transitioningDelegate = self;
  vc.modalPresentationStyle = UIModalPresentationCustom;
  [self presentViewController:vc animated:YES completion:nil];
  </code></pre>
