             Bug #: 50828
           Summary: class template parameter not printed for member
                    function template in candidate list
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: redi@gcc.gnu.org


template<typename T>
  struct A {
    template<typename U>
      void f() { }
  };

int main() {
  A<void> a;
  a.f(0);
}

With -fpretty-templates this gives:

f.C: In function âint main()â:
f.C:9:8: error: no matching function for call to âA<void>::f(int)â
f.C:9:8: note: candidate is:
f.C:4:12: note: template<class U> void A::f() [with U = U, T = void]

T is shown in the argument list, but not the signature. It should be:

f.C:4:12: note: template<class U> void A<T>::f() [with U = U, T = void]
                                        ^^^

For a non-template member function the class template parameter is shown
correctly.
