9314 - Calling "top.window.close()" from within a timeout crashes (in M7)

Status: VERIFIED FIXED

(Core :: DOM: Core & HTML, defect, P3)

Description

[tonyr]

(I had no idea which component to assign this to but since the code is in the DOM
directory...)

The following JavaScript attached to any window opened using
window.openDialog(...) causes a crash in nsGlobalWindow.cpp at line #1560, seems
like this would occur on all platforms but I don't currently have any way to
verify that.

--------------------------------------------
var intervalState = null;
var intervalCount = 0;
function OnLoadWindow()
{
	intervalState = setInterval( "OnInterval()", 100);
}

function OnInterval()
{
	// do something a few times
	intervalCount = intervalCount + 1;
	if (intervalCount > 10) {
		clearInterval( intervalState);
		top.window.close();
	}
}

-----------------------------------------

In GlobalWindowImpl::RunTimeout(...) after the timeout script is evaluated, it
calls "mContext->ScriptEvaluated()".  Apparently, the top.window.close()
JavaScript call causes mContext to become null which crashes.
