--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Don't both of those tests have UB (sure, we shouldn't ICE), using uninitial=
ized
non-static data member?
Perhaps:

int
bar (int &)
{
  return 1;
}

struct S {
  struct T {
    struct U {
      int i =3D bar (i);
    } p;
    void foo ();
  };
};

void
S::T::foo ()
{
  *this =3D {};
};

is better?=
