[Bug c++/35813] New: ICE with partial specialization of variadic templates

["sultansharem at gmx dot ch" <gcc-bugzilla at gcc dot gnu dot org>]

code,

template <int N, typename... P> struct i { typedef i t; };

template <typename I> struct n;

template <typename... E, int N> struct n<i<N, E...> > : i<N+1, E...> { };

template <typename... E> struct n<i<sizeof...(E), E...> > : i<sizeof...(E),
E...> { };

typedef i<1, char>  t;
typedef n<t>::t     x;

leads to "internal compiler error: tree check: expected tree_vec, have
type_pack_expansion in tsubst_copy_and_build, at cp/pt.c:10829"
