-O and -prof

Hi, Is there any reason not to use these options in combination? Out of habit, I don't usually combine them, but it'd probably be more interesting to do time profiling with optimized code, since the compiler tend to optimize away some of the more pedestrian stuff on its own. When I recently tried this, I got a surprising stack overflow -- surprising, as I don't get that with either option by itself. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
