Bug 98178 – using optgroup html tag on iPad causes Safari to crash

• Status: RESOLVED
• Resolution: INVALID
• Component: DOM

[Aaron]

Create a HTML drop-down list in a webpage and use the optgroup HTML tag. See here: http://www.w3schools.com/tags/tag_optgroup.asp

If you open this webpage using Safari on the iPad (tested on 4+ iPad 2's) and attempt to interact with the drop-down list by clicking on an option under the optgroup tag, Safari will crash and return to the homescreen, abruptly ending the browser's session.

I cannot reproduce a crash by opening the page, tapping "Try it yourself", and changing the value of the popup several times. Testes iPad and iPhone, both running iOS 6.

Please report this via <http://bugreport.apple.com> if you are still seeing this issue. We do not track issues specific to iOS in WebKit bugzilla.

Thank you for the bug report!

Sorry, I didn't intend for you to use http://www.w3schools.com/tags/tag_optgroup.asp to test the bug. I just wanted it as a reference to which HTML tag I was talking about. 

However after some experimenting I've realized this bug only occurs when there is an optgroup tag AND if the select tag has a SIZE.

Please go to http://www.w3schools.com/tags/tag_optgroup.asp again, click 'Try it yourself' then replace the content they have to the content below then click 'Edit and Click me:

<select>
  <optgroup label="Swedish Cars" size="5">
    <option value="volvo">Volvo</option>
    <option value="saab">Saab</option>
  </optgroup>
  <optgroup label="German Cars">
    <option value="mercedes">Mercedes</option>
    <option value="audi">Audi</option>
  </optgroup>
</select> 

Now if you attempt to choose an option from this new drop-down list via an iPad, the browser will crash. Hope that clears things up.

Accidentally set it to resolved when it isn't.

I cannot reproduce with this updated content either.

This was not accidental. As explained in comment 1, we do not track bugs specific to iOS here, please report it to Apple via http://bugreport.apple.com (unless you are also seeing the same issue in Safari or Chrome).

Our policy is to resolve iOS bugs reported here as INVALID.
