--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Thanks, Paolo. I've just realised the first line of the test case is missing,
sorry.
Here's a simpler form anyway:
template<class T>
struct A {};
template<class T>
void f(A<T>&) {}
struct B : A<long> {};
struct C : A<char> {};
struct D : B, C {};
int main()
{
D d;
f(d);
}
t.cc:16:6: note: ‘D’ is an ambiguous base class of ‘A<T>’
