   I'm having problems with virtual base classes:
   
   Script started on Thu May 11 18:53:46 1989
   jclark% cat test.c
   #include <stdio.h>
   
   struct A {
     int n;
     void set(int);
     void print();
   };
   
   void A::set(int i)
   {
     n = i;
   }
   
   void A::print()
   {
     fprintf(stderr, "%d\n", n);
   }
   
   struct B : virtual A {
   };
   
   
   main()
   {
     B *p = new B;
     p->set(5);
     p->print();
     fprintf(stderr, "p->n = %d\n", p->n);
   }

Here is what I get with this morning's compiler:

yahi% a.out
5
p->n = 5
