           Summary: remaining dependent base lookup
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: kreckel@ginac.de


G++ accepts this invalid code:

template <class T>
struct base {
     void f(void*);
};

template <class T>
struct derived : base<T> {
     derived() { f(this); } /* note: f(0) breaks g++, too */
};

struct instanced : derived<unsigned> {
     instanced() {}
};
