--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
It is fixed by that commit, and there are several tests for mixed volatile
pointers e.g.

+  volatile int i[2] =3D { 1, 2 };
+  volatile int j[2] =3D { 0, 0 };
+  int k[2] =3D { 0, 0 };
+
+  std::copy(i, i+2, j);
+  VERIFY( j[0] =3D=3D 1 && j[1] =3D=3D 2 );
+  std::copy(i, i+2, k);
   ^^^^^^^^^^^^^^^^^^^^^
