The following invalid code snippet causes an ICE on mainline.
=================================
template<typename T> struct A
{
typedef typename T::X Y;
};
A<int>::Y y;
=================================
bug.cc: In instantiation of 'A<int>':
bug.cc:6: instantiated from here
bug.cc:3: error: 'int' is not a class, struct, or union type
bug.cc:6: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in cp_parser_class_name, at cp/parser.c:12235
