Yes, memtest86 could only detect bad memory. No reported failure doesn't

There're several bugs known in gcc-3.2, some of them are removed in
gcc-3.3, some of them are scheduled to be fixed in gcc-3.4.
The best recommendation to optimization (if you don't want to research
atr gcc.gnu.org) is using -O and not more.
