Here's a short testcase that triggers the bug:

=============================================
template<typename> struct A {};

template<> struct A<void>
{
    template<typename T> void foo()
    {
        A<T> a;
        a.template foo<int>();
    }
};

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

With mainline I get:

bug.ii: In member function `void A<void>::foo() [with T = int]':
bug.ii:15:   instantiated from here
bug.ii:8: internal compiler error: in lookup_member, at cp/search.c:1228

With previous versions of gcc I get a decent error message.

According to Phil's regression checker, the regression was introduced
between 2003-07-08-trunk (#337) and 2003-07-09-trunk (#338).

(Since PR 10200 appeared before that date, I doubt that these two are related.)

Because this is invalid code I'm changing the keyword to ice-on-invalid-code.
But the original example should be revisited when the small testcase is fixed.
