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. Martin
