Summary: offsetof() crashes compiler

Initial Comment:
struct STR
{
  char c1, c2;
};

unsigned foo()
{
                                   // crash #1
  return (unsigned)  & (((struct STR      *) 0) -> c2);
                                   // ok
//return (unsigned)  & (((struct STR code *) 0) -> c2);
}

#define offsetof(TYPE, MEMBER)   \
 ((unsigned) &((TYPE code *)0)->MEMBER)

foo2 ()
{
	// crash #2, even with "code *"
  if (0 < offsetof(struct STR, c2))    ;
}
