Six cases return string constants, but the "default:" case returns NULL, so the %s could really get a NULL pointer. Happens with both gcc 14.1.1_p20240615 and 14.1.1_p20240622.

Please always include the full build.log and emerge --info. Anyway, please report this upstream (ideally with a PR given you've analysed it already). See also bug 803338.
