Well, maybe so, but it would be a pretty lame workaround. Why are you so worried about bugs? This flag was always disabled at -O1, and we have never seen any bug reports that got fixed with -fforced-mem. And besides, it is better to fix bugs than to work around them. Making the option a nop, issuing a warning in 4.1 and removing the option completely for gcc 4.2 looks like a very reasonable approach to me. Gr. Steven
