      Fix for Bug#38766 Falcon hangs during start-up if compiled for 64 bit SPARC
      
      Wrong CompareAndChange routine was used for in interlockedAdd. Replaced routine for exchanging 
      pointers with routine for exchanging integer values. This problem resultet in errors
      on big-endian 64 bit machines.

      Improve error handling in MemMgr::corrupt().
      Use FATAL macro instead of throwing BUG_CHECK. FATAL writes error text into 
      MySQL error log, uncaught exception can't do that.
