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