[comp.lang.c++] cfront bug in base class initialization

I would appreciate it if someone with cfront 2.1 would tell me if this bug
has been fixed in that release, as the problem has cropped up again:

    The following program demonstrates what is almost certainly a bug in cfront
    2.0.  The base class has two constructors, only the first of which is
    needed.  But if the second constructor is missing, then the first one is
    never called and the base part of the derived object doesn't get
    initialized.  

      #include <iostream.h>

      class Base  {
        public:
          Base(class Derived &p) { cout << "Base::Base -- 1\n"; }
          Base(Base &g) { cout << "Base::Base -- 2\n"; }
            // This second constructor is never called, but if it's not here,
            // then the first constructor won't be called and the Base part of
            // a Derived object will be uninitialized.
      };

      class Derived: public Base {
        public:
          Derived(): Base(*this) { cout << "Derived::Derived\n"; }
      };


      main()
      {
          Derived *pd = new Derived;
      }

All information appreciated,
