And I also fix a bug in my previous code. In my previous code, the
test_node in test case is:
typedef struct {
  Object_Control obj;
  int x;
}test_node;

It should be Chain_Node, not Object_Control here. However, because
Object_Control's size is bigger than Chain_Node, the test case doesn't
crash.
