Marc Fielding created CB-6138:
---------------------------------

             Summary: Use of overflow-x in app with iOS 6 Deployment Target results in iOS
6 device/sim crash
                 Key: CB-6138
                 URL: https://issues.apache.org/jira/browse/CB-6138
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 3.4.0
         Environment: iOS 6.x (multiple sub-versions) both simulated and on-device.  Xcode
5.0.2. OSX 10.9.2
            Reporter: Marc Fielding
            Priority: Minor


Steps to reproduce (100% chance):

1) create a new Cordova 3.4 project (e.g., "mybugsample")
2) add ios platform to cordova project
3) replace www/index.html code with the following:

//////////BEGIN SAMPLE///////////////
<!DOCTYPE html>
<html>
	<head>
	    <meta charset="utf-8">
	    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1,
minimum-scale=1, width=device-width, height=device-height, target-densitydpi=medium-dpi">
		<style>
			.app {
				-webkit-overflow-scrolling: touch;
			    height:100%;    
			    width:100%;    
			    padding:0px;     
			    margin:0px;  
			}
			td.myTD {
				overflow-x:hidden;
			}		
		</style>
	</head>
	<body>
		<div class="app">
		    <table>
		            <tr>
		                <td class="myTD">some text</td>
		            </tr>
		    </table>
			<script type="application/javascript" src="cordova.js"></script>
		</div>
	</body>
</html>
///////////////END SAMPLE//////////

4) Within project folder, perform "cordova prepare ios"
5) Within project folder, perform "open platforms/ios/mybugsample.xcodeproj"
6) Under the "General" tab in project properties, set the "Deployment Target" to "6.0".
7)  Clean, build, and run the app in an iOS 6.x simulator or on a 6.x device.
8) App will crash just after the splashscreen is displayed with the following error:

BTW, Jira lists Cordova 3.4 as an "unreleased version" :)

Thanks!
