--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
These are the ones which we don't catch right now:

#include <typeinfo>

int main () { }

typedef decltype (main) F; // xfail

F& foo () { return main; } // { dg-error "" }

int bar () { return main (); } // xfail

const std::type_info &ti = typeid (main); // xfail

const bool e = noexcept (main); // xfail

const int i = (main, 0); // xfail

template <F> struct A { };
A<main> a; // { dg-error "" }

template <F&> struct B { };
B<main> b; // { dg-error "" }
