           Summary: rejects legal, multiple inheritance (inheriting from
                    same class twice)
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: shuki_duv at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org

struct Base {
  int b;
  
  Base(int b) : b(b) { }
};

struct Derived : public Base {
  Derived(int d) : Base(d) { }
};

struct Final : public Derived, public Base {
  Final(int f) : Derived(f), Base(f-1) { }
};

int main()
{
  Final f(5);
}

gcc reports this as ambigous, although the ambiguity arises only when trying to
refer to Final via Base.
