--- Comment #5 from Paolo Carlini  ---
This variant causes the same ICE and it's a tad cleaner:

template  using a = void;
template  struct b
{
  typedef int c;
}; template  class b;
template ::c> class f;
template  class g { };
template  class h
{
  class i;
  typedef g j; class i
  {
j k;
  };
}; typename h::
