The following invalid code snippet triggers an ICE since at least GCC 2.95.3:
========================================
template<int> struct A
{
A();
};
template<int N, char> A<N>::A()
{
struct B {};
}
A<0> a;
========================================
bug.cc:6: error: got 2 template parameters for 'A<<anonymous> >::A()'
bug.cc:6: error: but 1 required
bug.cc: In constructor 'A<<anonymous> >::A() [with int <anonymous> = 0]':
bug.cc:11: instantiated from here
bug.cc:8: internal compiler error: tree check: accessed elt 2 of tree_vec with
1 elts in tsubst, at cp/pt.c:9048
Please submit a full bug report, [etc.]
