Mike, you make a good point about how an "obvious" bug can slip through. That's the first thing I thought when SAS crashed trying to compile a very simple BltBitMap call. But it turns out that the bug only shows up on 68000 Amigas when one of the parameters passed is an odd constant. It works on 020's and 030's, it works if it's even, and it works if the value is passed in as a variable. I could easily believe that SAS's test case for this (assuming there was one) happened to use an even constant, or a variable. But there's no excuse for the getcwd() example I described in a previous message. When compiled with registerized parameters, it always returned NULL (or maybe it was a null string) regardless of the various combinations of input parameters I tried. It was simply never tested.
