Bug with onClick.AddListener

It looks like i found a bug. Do you also have the same problem?

Demo Script: "PlayerAttackHandling"
public void StartAttack(int id)
{

Debug.Log("starting event for player attack " + id);​

}

Demo code in another script:
PlayerAttackHandling pah = newPlayer.GetComponent<PlayerAttackHandling>();
for (int i = 0; i<PlayerAttackButtonArray.Length; i++)
{

Debug.Log("set button listener" + i);
PlayerAttackButtonArray.onClick.AddListener(() => pah.StartAttack(i));​

}

I have 2 Buttons in this Test Scenario.
If i now klick the button0, it will write "id 2". But it should have id 0.
If i change it like the following lines, it will just work.
So i think thats a bug?

for (int i = 0; i<PlayerAttackButtonArray.Length; i++)
{

Debug.Log("set button " + i);
int test = i;
PlayerAttackButtonArray.onClick.AddListener(() => pah.StartAttack(test));​

}
