--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We support clang for all language levels, we just expect you to use a very
recent clang to work with newer language levels.

Since clang HEAD doesn't work with this code, making the function static seems
like the right solution.

Please send the patch to the gcc-patches and libstdc++ mailing lists, patches
do not get reviewed in Bugzilla.
