I remember the first time I ran into this was when I tried to run either Think C 
5 or 6 on my Power Mac 8600. Very excited about the move up from coding on a 
IIci and the resulting shorter compiling times, I hit the shortcuts for running 
my code and ... a hard crash followed. Reboot, tried again and same result.

Given I had moved the code over from the IIci and *knew* it runs, it had to be a 
Think C problem. Some online research later confirmed that.
