Description

Opening a simple app with a tabgroup crashes 1 times out of 4 in 1.9.0 V8. Does not occur in iOS, 1.9.0 Rhino, or 1.8.1 V8/Rhino. Could not produce in 1.9.0 V8 default app (5 trials). Steps to Reproduce: 1. Run code.

var win = Ti.UI.createWindow({
	backgroundColor: 'red',
	fullscreen: false,
	exitOnClose: true
});

var button = Ti.UI.createButton({
	height: 50,
	title: 'click'
});

button.addEventListener('click', function(e)
{
	var tabGroup = Ti.UI.createTabGroup();
	
	var	tabWin = Ti.UI.createWindow({
			title: 'blue',
			backgroundColor: 'blue'
		});
	
	var	tabButton = Ti.UI.createButton({
			title: 'close'
		});
	
	var	tab = Ti.UI.createTab({
			title: 'blue',
			window: tabWin
		});

	tabWin.add(tabButton);
	
	tabButton.addEventListener('click', function(e){
		tabGroup.close();
	});
	
	tabGroup.addTab(tab);	
	tabGroup.open();
});

win.add(button);
win.open();

2. Click 'click' and 'close' 10 times. Expected Result: No blank screen freezes or immediate crashes, but there may be a null pointer crash after a force close dialog (separate issue). Actual Result: Crash with debug output usually including the line: committing suicide to free the zombie. Log attached. Screen may remain black and console prints empty-window errors on click. Note: The sample code without the above test harness still crashes, excerpt below:

var tabGroup = Ti.UI.createTabGroup();

var tabWin = Ti.UI.createWindow({
		title: 'blue',
		backgroundColor: 'blue'
	});

var tabButton = Ti.UI.createButton({
		title: 'close'
	});

var tab = Ti.UI.createTab({
		title: 'blue',
		window: tabWin
	});

tabWin.add(tabButton);

tabButton.addEventListener('click', function(e){
	tabGroup.close();
});

tabGroup.addTab(tab);	
tabGroup.open();
