title: React Native App Debug mode works fine, Release mode crashes (App Registry and evaluating 'a.View.propTypes.style')
body: <p>I've been implementing map box recently, and I've updated to the latest version of react-native, gradle, and what not. The app runs absolutely fine in debug mode, but as soon as I run it in release mode it crashes immeidately with no warning screen at all. I'm using the new propTypes, and so on.</p>
  
  <p>Please see the output log</p>
  
  <p>Okay I apologise, whilst the above works in debug mode, the app is now crashing when building a release and I'm confused.</p>
  
  <p>I'm attempting to build a release, and the crashes immediately although works fine in debug mode:</p>
