To the Zortech guys (Walter Bright ?) , the following question:
 The following program should print a 'B' , but the output is a D.
 Any fixes ?
 
 
I enjoy your product (1.07) but this problem kept a program from running
for a while.


#include <stdio.h>
 
class B{
public:
 virtual f() { return 'B';}
 virtual g() ;
  };
 
class D: public B{
 public:
  D() { putchar(B::g()); }
  f() {return 'D'; }
  g() { }
  };
 
 static h(B * t)
  { return t->B::f();
  }
 
 B::g(){ return h(this); }
 
main()
 { D d;
   puts("finished\n");
   }
