Just had a look through the 11 fails - as far as I can tell none of them are related to this change. There's still two pending builds (`libc-riscv64-debian-dbg`, `sanitizer-x86_64-linux-fast`), though IMO it seems unlikely those configurations will pick up a problem with this patch that others have missed.

Happy to wait longer or wait for another pair of eyes, whatever you think is best!
