In version 1.36.0- on a Sun 4, running 4.0.1, the program foo.cc


  class cl* my_allocater(int size);
  void my_free(class cl* ptr);

  class cl {
  public:
     cl() {
       this = my_allocater( sizeof(cl) );
     };
     ~cl() {
       my_free( this );
       this = 0;
     };
  };

Gets the following errors
