make: *** [sendmsg.lo] Error 1

Here's a testcase:

typedef const struct objc_selector
{
  void *sel_id;
  const char *sel_types;
} *SEL;

typedef struct objc_object {
  struct objc_class* class_pointer;
} *id;

static id
__objc_word_forward (id rcv, SEL op, ...)
{
  void *args, *res;

  args = __builtin_apply_args ();
  res = __objc_forward (rcv, op, args);
  __builtin_return (res);
}

This reproduces the ICE with a cross cc1. No optimization flags are necessary.
