The generated assembly was garbage, so I assume it was a compiler bug. It also got fixed in later revisions, but since the compiler is shipped with the CRT... :) I don't actually recall if we were using the shipped CRT or not, I'm guessing only minimal parts of it were used, if any, since embedded projects tend to write their own subset of the needed standard library functions.
