title: How to diagnose EXC_CRASH?
body: <p>A tester sent this crash file:
  Not sure what an EXC_CRASH is.</p>
  
  <p>UPDATE:
  I can randomly replicate it on device (never in simulator) when rotating my phone. Here is my rotation code:</p>
  
  <pre><code>// Override to allow orientations other than the default portrait orientation.
  - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
  
      if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
  
          imageScrollView.frame = CGRectMake(0,0,480,300); //self.view.bounds;
          imageView.frame = CGRectMake(0,0,480,300); //self.view.bounds;
      }
      else {
          imageScrollView.frame = CGRectMake(0,0,320,460); 
          imageView.frame = CGRectMake(0,0,320,460); 
      }
  
  
      //return (interfaceOrientation == UIInterfaceOrientationPortrait);
      if (enableLandscapeOrientation) {
          [[self navigationController] setNavigationBarHidden:UIInterfaceOrientationIsLandscape(interfaceOrientation) animated:YES];
          return YES;
      }
      else {
          return NO;
      }
  }
