currently i use (in my code):
  ECMA_BEGIN_FUNC(hashObject)
  {
    ECMA_CHECK_NUM_ARGS(1);
    if (!JSVAL_IS_OBJECT(argv[0])) ECMA_ERROR("object required as
argument");
    JSObject *o=JSVAL_TO_OBJECT(argv[0]);
    if (!o) return JS_FALSE;
    *rval=INT_TO_JSVAL(o);
    return JS_TRUE;
  }

are object pointers guaranteed to remain constant during the lifetime of
a object?

i will try your patch
