The following invalid code snippet causes an ICE since at least gcc 2.95.3:

==============================
template<typename T> struct A
{
    template<T&> struct B;
};

A<void> a;
==============================

bug3.cc: In instantiation of 'A<void>':
bug3.cc:6:   instantiated from here
bug3.cc:3: error: forming reference to void
bug3.cc:3: internal compiler error: tree check: expected tree_vec, have
error_mark in retrieve_specialization, at cp/pt.c:822
Please submit a full bug report, [etc.]

Using "int&" instead of "void" to instantiate the template also causes
an ICE.
