Description Clement Wehrung 2013-12-11 05:40:18 PST 
Working on a project with JavaScriptCore I get repeated crashes with EXC_BAD_ACCESS from WebCore::setSharedTimerFireInterval(double). Is there any way to be more specific ? I could try to build a separate project to show the bug in action. I can reproduce very easily with my project. I'm only sharing one objc Class with JS.
