			Jaehyun_ChoUnsubmitted Not Done Reply It seems that there is a reason why this memory initialization is required only for debugging mode. But I don't know why.. Could you tell me the reason? Jaehyun_Cho: It seems that there is a reason why this memory initialization is required only for debugging…

			Jaehyun_ChoUnsubmitted Not Done Reply Thank you. It seems that it purely helps the debugging ;) e.g. alloca() does not initialize memory so it seems that the initial dirty memory may make debugging difficult. Jaehyun_Cho: Thank you.
