For > example I noticed a significant difference on the OpenSUSE distro when GCC was There may also be some regressions that cause newer gcc's to miscompile some previously working code due to a corner-case in some newly introducted optimization. Rare, but does happen. I've reported a few myself over the years, and while the gcc people are extremely good at tracking these down, I'd feel much more comfortable if a mass rebuild got done early on, just to be sure. "Problem started after mass recompile" is much so much easier to diagnose than "Problem started after bumping package from 1.1 to 1.2 (or even 1.1-1 to 1.1-2 where we just fixed typos in the documentation". -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
