   I appear to have 1.52C as per the name of the CD,   
   even though the label says 1.52.   
      
   Anyway, I believe I have found a compiler bug:   
      
   /*   
      
   This program demonstrates a presumed bug in Visual C++ 1.52C   
      
   When compiled with:   
      
   cl -Fa -c -AH -Ox -f foo.c   
      
   it says it generated:   
      
   add     bx,ax   
   mov     BYTE PTR ss:[bx],OFFSET 88   
      
   but looking at the object code shows:   
      
   03D8 C60758   
      
   Manually assembling with masm shows:   
      
   03 D8				add	bx,ax   
   36: C6 07 58			mov	BYTE PTR ss:[bx],OFFSET 88   
      
   the '36' is the SS override. That is missing from the object code.   
   This only becomes a problem if ds and ss are not the same. Normally   
   they are the same.   
      
   */   
   void foo(int y)   
   {   
       char buf[4];   
      
       buf[3-y] = 'X';   
       bar(buf);   
       return;   
   }
