Summary: GCC claims a friend function to be overloaded, but it
isn't
Classification: Unclassified

Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org

template <typename T>
class rp {
};
template <template <typename> class P>
struct b {
template <class, template <typename> class FriendP>
friend void f(b<FriendP> from);
};
template <class, template <typename> class P>
void f(b<P> from) {
}
int main() {
b<rp> v;
f<int>(v);
return 0;
}

> gcc map.cpp
main.cpp: In function 'int main()':
main.cpp:17:13: error: call of overloaded 'f(b<rp>&)' is ambiguous
f<int>(v);
^
main.cpp:17:13: note: candidates are:
main.cpp:12:6: note: void f(b<P>) [with <template-parameter-1-1> = int; P = rp]
void f(b<P> from) {

main.cpp:8:17: note: void f(b<FriendP>) [with <template-parameter-2-1> = int;
FriendP = rp; P = rp]
friend void f(b<FriendP> from);

I can't see an overload here.
