--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
(In reply to Michael Gorbovitski from comment #2)
> Slightly simplified test case (no need for double-argument template):
here is one which is valid C++98 which shows even GCC 4.1.2 has the same ICE
struct foo{};
template <class A> struct friender {
typedef foo cls;
};
class bar {
template <class X>
friend class friender<X>::cls;
int hidden;
};
int main() {
bar b;
}
---- CUT ----
Oh and clang does not support it fully either, it just turns off the access
checking for bar.
