title: Xcode 7: crash on breakpoint stop
body: <p>I have an extremely annoying problem!
  Xcode 7 crashes almost on every breakpoint when it tries to symbolicate.</p>
  
  <p>I have done several things including deleting Xcode and reinstalling it...</p>
  
  <p>I also had the same issue on the previous Xcode 6.X</p>
  
  <p>Any clue? I am wondering if I should reinstall mac OS from scratch...</p>
