The strength reduce problems on Intel and other platforms with small register sets have not been fixed. The example program that demonstrates the bug changes in subtle ways from release to release but it isn't fixed yet. I'd add -fno-strength-reduce if you just HAVE to use -O2. I've been bitten by the bug too many times so I stick with -O for everything. -- Note: See http://www.members.home.net/graywane/ for PGP information.
