--- Comment #9 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
But even that won't work for Wdangling-reference6.C where the argtype is int
but the rettype is std::pair<const int&, const int&>.

Really, all I could do is to warn only when all the arguments to the functi=
on
returning a reference are temporaries, e.g. don't warn on

f(a, a);
f(a, 42);
f(42, a);

only on

f(42, 42);=
