Could you please provide us the test steps/directions to check this issue?
Comment 2 Chris Hamons 2014-09-30 10:52:20 UTC
Create an app with a button

Have this code in the awake from nib:

this.Window.StandardWindowButton(NSWindowButton.CloseButton).Activated +=
(object sender, EventArgs e) => {
Console.WriteLine (foo); }

Have the button gc.collect(2);

Click button
Click close button
You should crash since the called back button returned from this.Window.StandardWindowButton was collected.
