I can crash Safari 419.3 with the following HTML: <div id="a"><input type=checkbox onchange="prefill();"></div> <script> function prefill() { var elm = document.getElementById("a"); elm.innerHTML = "<input type=checkbox>"; elm.firstChild.onchange = prefill; } </script>

This does not crash with ToT WebKit. As expected, the checkbox remains unchecked when clicked.
Out of curiosity, should I continue to file new bugs which crash Safari 419.3, but which don't crash nightlies? This has been the case for both this bug and bug 12191. If I am wasting your time, then please let me know. By the way, I found another crasher for 419.3 (safe on nightlies again) with this HTML: <a href="javascript:doit();">click me</a> <div id="menu" style="overflow:auto"></div> <script> function doit() { var m = document.getElementById("menu"); document.body.appendChild(m); m.style.display = "none"; m.scrollTop = 0; } </script>
