This appears fixed on trunk but not in the last 14 snapshot (20231029). Not
sure if it got really fixed or is now latent, so reporting just in case so can
bisect for the fix later if it's not an obvious dupe.

Originally reported downstream by Kostadin Shishmanov in
https://bugs.gentoo.org/916860. Interestingly, it is the same source file as in
PR112380 (which still occurs on trunk).
