--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC uninit warning for decls whos address has been taken is weak which is the
first one GCC does not warn.  The second one should not be warned due to C++17
order of execution rules changes (there is no reason not apply them to earlier
C++ versions really).
