As has been pointed out by the community, there is an existing crash bug that was reported by Matthew Dempsky in the Flash Player bugbase (JIRA FP-677) in September of 2008 that still exists in the release players. It is fixed in Flash Player 10.1 beta, and has been since we launched the beta in early November 2009. [...] So what happened here? We picked up the bug as a crasher when it was filed on September 22, 2008, and were able to reproduce it. Remember that Flash Player 10 shipped in October 2008, so when this bug was reported we were pretty much locked and loaded for launch.
