--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, the reason that -fcompare-debug fails isn't that -g vs. -g0 would emit
different line number, but that -fcompare-debug uses -w for one of the
compilations so that warnings aren't emitted multiple times and so one
compilation is with -Wmissing-template-keyword and one without.
