Confirmed.
It works fine if you rewrite it without alias templates:
template<int...I> struct NumList { typedef List< Z<I...> > type; };
then use NumList::type instead of NumList, so the problem is with the alias
template substitution.
G++ seems to be treating Z<I>... as Z<I...> in the type-id of the
alias-declaration.
