The following invalid code snippet triggers an ICE since GCC 3.4.0:

===========================================
template<typename> struct A
{
    template<int> void foo()  // missing ;
};

template<> struct A<void>
{
    template<int> void foo();
};

void bar()
{
    A<void> a;
    a.foo<0>();
}
===========================================

bug.cc:4: error: expected initializer before '}' token
bug.cc:6: error: explicit specialization in non-namespace scope 'struct A<
<template-parameter-1-1> >'
bug.cc:6: error: enclosing class templates are not explicitly specialized
bug.cc:6: error: template parameters not used in partial specialization:
bug.cc:6: error:         '<template-parameter-1-1>'
bug.cc:15: error: expected `}' at end of input
bug.cc: In member function 'void A< <template-parameter-1-1> >::bar()':
bug.cc:14: internal compiler error: in retrieve_specialization, at cp/pt.c:819
