The following invalid code snippet triggers an ICE on mainline:
===================================================
struct A
{
template<typename... T> struct B;
};
template<typename... T> struct A::B<T*> {};
===================================================
bug.cc:6: error: parameter packs not expanded with `...':
bug.cc:6: note: 'T'
bug.cc:6: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in cp_parser_class_head, at cp/parser.c:14654
Please submit a full bug report, [etc.]
