The problem turned out to be an uninitialized Boolean variable. So, depending upon the active memory contents, the compiled code, etc. there was a 50-50 chance that it would behave one way or the other. Normally it was behaving as False (the desired value), but when it went badly and the bug appeared, it was behaving like it was True.
