title: Xcode 7: exception breakpoint firing in `main.m`, but app runs normally
body: <p>I've set an "All Exceptions" exception breakpoint for my project. In Xcode 7, it mysteriously fires on launch in <code>main.m</code>, but there doesn't seem to be anything obviously wrong. On continuing, the app runs normally.</p>
  
  <p>Even running the project in Xcode 6 now causes this breakpoint to fire. </p>

  <p>I can't figure out what is causing this. The threads don't indicate anything specific to what the cause is.</p>
  
  <p>Maybe it's some sort of font issue in the Storyboard or something? Does anyone know a fix?</p>
  
  <p><strong>NOTE:</strong> It's a C++ exception, not Objective-C. Perhaps due to missing fonts. <a href="https://stackoverflow.com/questions/26127004/xcode-throws-an-exception-in-main-in-ios-8-with-all-exceptions-breakpoint">Xcode throws an exception in Main() in iOS 8 with &#39;all exceptions&#39; breakpoint</a></p>
