--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
This variant also ICEs on trunk:
% cat cr.ii
template <int> struct ops {
template <int> struct A;
template <int *Ptr> using explode = typename A<*Ptr>::join;
};
template <typename Ts> ops<'\0'>::explode<Ts::join> a;
% g++ -c cr.ii
cr.ii: In substitution of ‘template<int <anonymous> > template<int* Ptr> using
explode = typename ops<<anonymous> >::A<(* Ptr)>::join [with int* Ptr = Ts::
join; int <anonymous> = 0]’:
cr.ii:5:51: required from here
cr.ii:3:61: internal compiler error: Segmentation fault
template <int *Ptr> using explode = typename A<*Ptr>::join;
