Don't sound so surprised. 8) Don't all compilers have optimization bugs? I mean, if they didn't, then they'd probably just optimize the code without you asking. I think Borland C++ (3.0-5.0) used to have some optimization bugs. You know what the best optimization is? Replacing those bubble sorts with quicksorts, etc. Basically, optimization levels above -O are not supported, so if you have problems, it's not our fault. 8-) Basically, stay away from optimizations with mission-critical stuff such as the kernel and userland. For ports, it's OK. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
