Are you sure about that? I’m not aware of any additional UB exploitation enabled by O3 vs O2 or Os.

- MyOutfitIsVague 2y agoNope, I'm not sure about it. I remember when I was using Gentoo about 10 years ago, this was the common reason given for using -O2 instead of -O3 in your build flags, and I'm just speaking from that memory.
- vlovich123 2y agoYeah there’s lots of cargo culting FUD like that that happens (see other posters in this thread that claim that glibc is a more stable allocator )
