<pre>Clang incorrectly accepts this invalid C++:
class Y {
template<typename T> friend class X;
template<typename U>
static bool equals(U const&, U const&) { return true; }
};
template<typename T>
class X {
public:
friend bool operator ==(X const& lhs, X const& rhs) {
return Y::equals(lhs, rhs);
}
};
void test(X<int> x) {
if (x == x) { }
}
"operator ==" should not be allowed to access Y::equals(), because a friend
function definition is not a member of the class. GCC and EDG properly diagnose
this ill-formed code.</pre>
