Hi Martin, I'm not very familiar with iOS, but it looks like there was a bad dereference inside of the WebView (that 0xfffffff9 looks like the highest address on your process stack).
I did get it to fail in the ios simulator as well, but mobile safari only reports a "bus error", which suggests that this is a bad pointer dereference. I have a hunch that this is related to a node being removed from the DOM that also has a touch listener on it, but that idea is just based on the fact that safari stops sending touch events when the origin node is removed. The WebCore::Document::touchEventsChangedTimerFired code is an IOS only extension to WebKit, so I'm not sure how to look at what that is doing.
