The following program causes a compiler crash.  Hopefully it
is not due to my minor compiler mods.

------------- bug.cc ----------------
class Object {
public:
  virtual int foo(int n);
};

class Pointer : public Object {
  Object* _object;
public:
};

typedef struct {
  int timestamp;
  int first_line;
  int first_column;
  int last_line;
  int last_column;
  char *text;
} yyltype;

short *yyr2;

int
yyparse()
{
  Pointer *yyvsp;
  yyltype  yylsa[200 ];	 
  Pointer yyval;		 
  int yylen;

  yylen = yyr2[0];
  yyval = yyvsp[1-yylen];  
}
-------------------------------------

------------ output -----------------
