--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase for -O2 -g -fdebug-types-section:
struct A {};
namespace N {
struct B {
  using C = struct H {};
  using D = A;
};
}
struct E : N::B {
  typedef C C;
};
namespace N {
struct F {
  E::C d;
  E::D h;
};
}
struct G {
  N::F i;
} j;
