Is it possible that is related to your warning patches?
Yes, this is likely the same bug as mentioned in comment #6 on
pr77676. The bug in the comment ILP32-specific and only tangentially
related to the PR itself. I'm testing the patch that's attached to
the PR that should fix both of these problems. I don't have access
to i?86-unknown-freebsd so if you could help validate it there I'd
be grateful. (The patch just successfully bootstrapped on
i386-pc-linux-gnu.)
Thanks and sorry for the breakage.
