--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> --- Hmm, 17_intro/names.cc is supposed to test libstdc++ not libc headers. But running it again with _FORTIFY_SOURCE defined is really only going to find problems in Glibc, and that test belongs in Glibc itself. Anyway, patch posted: https://gcc.gnu.org/pipermail/gcc-patches/2024-October/664507.html
