            Bug ID: 105047
           Summary: invalid non-dependent call to non-static member of the
                    current instantiation not rejected ahead of time
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ppalka at gcc dot gnu.org
  Target Milestone: ---

Accepts-invalid testcase:

template<class>
class A {
  void f();

  static void g() {
    f();  // invalid because 'this' unavailable
  }

  void h() {
    f(0); // invalid because wrong # of arguments
  }
};

We probably should be able to reject both calls to f ahead of time.
