Summary: Clang doesn't consider conversion function template
friends.
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]

Clang doesn't like this, saying that "u.m_a" is private.
template <class T>
class A
{
public:
template <class U>
operator A<U>() {
A<U> u;
u.m_a = m_a;
return u;
}
template <class U> template<class V>
friend A<U>::operator A<V>();
private:
int m_a;
};
void f() {
A<int> a = A<double>();
}
There seems to be poor support for such friends. Comeau fails with an ICE
assertion failure and GCC doesn't like it either.
I believe this program is correct according to the Standard (however the
Standard says that you can define function template friends in the friend
declaration - this can't be true for member function templates. Sounds like the
text treats "member function template" and "member template" as being mutually
exclusive?).
If this is indeed not valid, it would seem to be a good thing to reject this
straight away when the template is parsed.
