We could not print Anchors.
---
We changed our methods which is global function, today.
dummy_vPoint_index++ before return, so, which ensured next value is dummy_vPoint[dummy_vPoint_index];
And we could see if dummy_vPoint[dummy_vPoint_index] is nullptr before return.
This is O.K.
Memorization error is another reason.
