Please include the info from the wiki page I linked you if possible. There’s a lot but it’s needed.
Comment 2 Geoff Leach 2020-12-16 07:36:12 UTC 
Yes, I've looked at that page before, and blanched :), but might be time to step it up!
Comment 3 Sergei Trofimovich (RETIRED) gentoo-dev 2020-12-16 07:41:50 UTC 
Reproduced locally. I'll extract smaller example and attach to https://gcc.gnu.org/PR97750.

Added as https://gcc.gnu.org/PR97750#c3
Comment 5 Sergei Trofimovich (RETIRED) gentoo-dev 2020-12-17 16:37:57 UTC 
gcc was fixed upstream with https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=c25b504636fec7bf8f181a84af83a52757ba7e89

We'll also need to refresh gcc patchset to avoid patches conflicts.

Should be sorted by https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=badb26541f1acfca59f4dab726694d41fa819c56
