Reduction:
<div>
 <input value="foo"></input>
 <iframe frameborder="0" id="input" height="100" width="540" srcdoc="&lt;input autofocus>"></iframe>
</div>
<script>
addEventListener("change", function(e) {
    document.body.appendChild(document.getElementById("input"));
    document.body.appendChild(document.createTextNode("PASS"));
}, false);
</script>


1. Open the above document
2. Click on the left input field
3. Modify it
4. Click on the right input field
 --> Crash by null pointer deference
