--- Comment #2 from anlauf at gcc dot gnu.org ---
Works on 14-mainline, and on 13-branch since at least r13-8285.
Likely due to one of the associate-fixes.

Updating known-to-work and known-to-fail.

In principle this bug has been fixed and could be closed.

Fails with 11.2.1 20210728 and is OK with 12.2.1 20230321.

Thanks for the report Gerhard. I think that we can shut this one down.
