The following invalid code snippet causes an ICE on mainline:

=============================
template<int(> struct A;
=============================

bugA.cc:1: error: expected `)' before '>' token
bugA.cc:1: internal compiler error: tree check: accessed elt 1 of tree_vec with
0 elts in get_innermost_template_args, at cp/pt.c:490
Please submit a full bug report, [etc.]


A similar testcase causes an ICE in a different function:

=============================
template<typename> struct A
{
    template<int(> struct B;
};

A<char> a;
=============================

bugB.cc:3: error: expected `)' before '>' token
bugB.cc: In instantiation of 'A<char>':
bugB.cc:6:   instantiated from here
bugB.cc:3: internal compiler error: tree check: accessed elt 1 of tree_vec with
0 elts in add_outermost_template_args, at cp/pt.c:459
Please submit a full bug report, [etc.]

The second testcase also ICEd before GCC 3.4.0.
