title: OpenGL ES Application Template Project Crashes in iOS Simulator
body: <p>I am new to OpenGL ES 2.0.</p>
  
  <p>I create a new project from XCode "OpenGLES Application Template", and try to run it, but it crashes in the iOS Simulator. When I debug it, I can see it draws the first cube successfully but then it goes somewhere which I can't see, and application crashes. I can not see any error reported in the console.</p>
  
  <p>Some info:
  My Xcode version is 3.2.6,
  iOS Simulator is 4.3,
  Running on Mac OSx 10.6.8,
  iOS 4.3 SDK.</p>
  
  <p>Thanks in advance :)</p>
