title: Unity engine crash 4.2 and 4.3: Execution Engine Exception SIGILL
body: <p>I am facing a problem, I have created a scene in my game and when I focus on a particular game object (clicking on it or going to that particular game object ). When I do that the unity engine simply crashes. In unity 4.2 system hangs (on mac and windows as well) and on 4.3 it hangs by showing the error <a href="http://i.stack.imgur.com/kPntM.png" rel="nofollow">attached error</a>. <a href="http://i.stack.imgur.com/0P4Tg.png" rel="nofollow">specific error</a>.</p>
  
  <p>Any help would be really appreciated, as I am stuck on it for last 48 hours, and I simply cannot continue the development further.</p>
  
  <p>Thanks in advance.</p>
