[Bug c++/13907] New: pedantic needed to disambiguate

["japple at freeshell dot org" <gcc-bugzilla at gcc dot gnu dot org>]

struct A {
  operator int & ();
  operator const int & () const;
};
                                                                               
          
void f(int &);
void f(const int &);
                                                                               
          
int main() {
  const A x = A();
  f(x);
}

gives

const_overload.cpp: In function `int main()':
const_overload.cpp:12: error: call of overloaded `f(const A&)' is ambiguous
const_overload.cpp:7: error: candidates are: void f(int&)
const_overload.cpp:8: error:                 void f(const int&)

unless -pedantic is set.
