<pre>On the following code clang gives error:
1.cpp:16:26: error: use of class template y requires template arguments
friend void x<U>::f(y);
^
But gcc and msvc compiles this code without any error.
template <typename U>
struct y;
template <typename T>
struct x
{
void f(y<T> a)
{
a.a = 5;
}
};
template <typename U>
struct y
{
friend void x<U>::f(y); // error here
private:
int a;
};
int main()
{
x<int>().f(y<int>());
}</pre>
