[TIMOB-18253] iOS: Debugger crashed when the variable value is changed to random object

- Put a breakpoint at line 3 in the below code.

function doClick(e) {
	var txt = "labelTxt";
    alert(txt);
    print(e);
}

function print(e) {
	Ti.API.info('info');
    Ti.API.warn('warn');
    Ti.API.error('error');
}

$.index.open();

- Debug the app onto iOS device or simulator. - Click on the label, so that the thread suspends its execution at line 3. - Now, change the value of 'txt' to "changed". Press F8 (Resume). The dialog shows the message "changed". It works ! Click on the label again to suspend the thread at the same line. Now, change the value of 'txt' to _changed_. Press F8 (Resume). The debugger/app will crash.
