--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
(In reply to Jonathan Wakely from comment #2)
> G++ does not give an error for the example in p5:
>=20
> class A { /* ... */ };
> void (*pf1)(); // no exception specification
> void (*pf2)() throw(A);
>=20
> void f() {
>   pf1 =3D pf2; // OK: pf1 is less restrictive
>   pf2 =3D pf1; // error: pf2 is more restrictive
> }
>=20
> That should be ill-formed in C++98/11/14.

The above testcase is PR 12255.
