title: SIGBUS crash only on Samsung Galaxy S2
body: <p>I've got a very strange problem - my works well on all devices, but occasionally crashes on Samsung Galaxy S2.</p>
  
  <p>The app uses ffmpeg and crash is somewhere there. However, I can't see any problem in the code itself (if there was, it would crash on other devices as well).</p>
  
  <p>I tried to compile with all asm-optimizations off, but still doesn't help.</p>
  
  <p>It also seems that the crash happens only on 2.3.6 and doesn't crash on ICS.</p>

  <p>Has anybody seen anything strange with the device or that particular Android version?
  Or any suggestions where to look and how to fix?</p>
