Created attachment 734287 [details] GCC build logs Build logs.
Few things of note here, I suppose: - CFLAGS="-O2 -march=native -fomit-frame-pointer -fno-stack-protector -pipe" I personally wouldn't consider -fno-stack-protector to be a sensible or supported configuration. I wouldn't be surprised if plenty of stuff fails to build with this, and at least in the case of GCC, if it ended up forcing it on/off for some specific subcomponents, and this could end up being the cause (which may end up being a minor bug in GCC if it should filter it better). - LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common -Wl,--relax" -Wl,--relax is rather uncommon. Interestingly, slyfox raised it in a ::haskell bug (https://github.com/gentoo-haskell/gentoo-haskell/issues/704) and ended up filing a bug for binutils itself to better handle some mixed situations (similar to what I'm describing for -fno-satck-protector): https://sourceware.org/bugzilla/show_bug.cgi?id=27837. - I would not particularly bother with gold any more at this point, given it seems rather low-activity upstream. (As a complete aside, it seems rather odd to me you have so many Pythons, autoconfs, and automakes installed. Please remember to depclean after world upgrades and avoid putting dependencies/things you don't personally want in your /var/lib/portage/world file.)
(In reply to Sam James from comment #2) > Few things of note here, I suppose: It would be useful if you could first tell us: - if the failure occurs with "vanilla" CFLAGS + CXXFLAGS + *FLAGS + LDFLAGS; - if it occurs with gold; - if previous GCC versions work. Depending on the results, we can figure out exactly which specific options cause failure.
After updating pretty old Gentoo installation, I got stuck with GCC upgrade. Latest 8.5.0-r1βis compiling just fine, but any from 9,10,11 branch is failing with the same "differs" issue.

Also, in the new bug, include emerge --info, and a tarball of the whole workdir.
(In reply to Sam James from comment #6) > Please file a new bug as this is for 11.2.0 and your version is > 11.2.1_p20220115. As I said, looks like it's version-independent issue, because it's reproducible on any of 9,10,11 branches. But I was able to resolve this issue. Reading the links you provided and more, I found suggestion this can be related to CFLAGS, indeed, I changed it from CFLAGS="-O2 -pipe -march=native" to (I have old Opteron) CFLAGS="-O2 -pipe -march=bdver2" And now it compiles flawlessly! Thanks a lot! I can still provide a tarball of working copy, if it can help to make upstream fix.
