title: Native crash at /dev/ashmem/dalvik-jit-code-cache
body: <p>I'm getting crashes from numerous devices for a native crash for my Android game, GeoGuess (<a href="https://play.google.com/store/apps/details?id=uk.co.quinny898.game.geoguess" rel="nofollow noreferrer">https://play.google.com/store/apps/details?id=uk.co.quinny898.game.geoguess</a>)</p>
  
  <p>It's all Java, so I don't see why this crash is happening. The crash is on 34 unique devices (and counting) and is really causing problems for users (it appears to be on launch)</p>
  
  <p>The stack trace is as follows:</p>
