Test case\r\n\r\nWhen using an unmodified 1.8.20111028x CI build, the following testcase generally crashes with EXC_BAD_ACCESS after 2 to 10 presses of the \"Start Test\" button.\r\n\r\n{code:lang=javascript|title=app.js}\r\nvar root = Ti.UI.createWindow({\r\n  title: 'Root Window',\r\n  backgroundColor: 'white',\r\n  layout: 'vertical',\r\n});\r\n\r\nvar startButton = Ti.UI.createButton({\r\n  title: 'Start Test',\r\n  height:'50dp',\r\n  width:'200dp',\r\n  top:'20dp',  \r\n});\r\nstartButton.addEventListener('click', function() {\r\n  // for (;;) {\r\n    var windows = [], n = Math.floor(Math.random() * 10) + 3;\r\n    for (var i=0; i < n; i++) {\r\n      var w = Ti.UI.createWindow({\r\n        title: 'Window '+i,\r\n        backgroundColor: 'white',\r\n        layout: 'vertical',\r\n      });\r\n      windows.push(w);\r\n      navgroup.open(w, {animated:false});\r\n      Ti.API.info('opened '+w.title);\r\n    }\r\n    \r\n    while (windows.length > 0) {\r\n      var winToClose = windows.pop();\r\n      navgroup.close(winToClose, { animated: false});\r\n      Ti.API.info('closed '+w.title);\r\n    }\r\n  // }\r\n});\r\nroot.add(startButton);\r\n\r\nvar navgroup = Ti.UI.iPhone.createNavigationGroup({\r\n  window: root\r\n});\r\n\r\nvar container = Ti.UI.createWindow();\r\ncontainer.add(navgroup);\r\ncontainer.open();\r\n\r\n{code}\r\n\r\nh2.
