--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'd say it is a user bug, you shouldn't use gnu_inline attribute on a function
that is not extern inline.  Why do you want that?  Either you want extern
inline __attribute__((gnu_inline)), which will act as the GNU extern inline
function (if inlined successfully, fine, otherwise you need to supply external
definition), or you want normal C++ inline semantics.  inline
__attribute__((gnu_inline)) doesn't make sense.
