title: XCode 3.2.6 hangs up
body: <p>My Xcode 3.2.6 is hanging up constantly.
  While I'm coding with no apparent reason it starts consuming more and more CPU, CPU temperature rises up to 80 celsius, the fan get exhausted and I'm forced to "force-quit" it and relaunch it to be able to continue working... 
  It start happening this week and nobody else on my project is having the same troubles.
  My OS is Snow leopard 10.6.8 
  Any ideas on what could be happening?</p>
