Yes, I had it a few times in the beta after upgrading through Steam.
After getting frustrated by it persisting, I completely uninstalled the beta. Oddly enough, as I was doing that, I was also notified about an update for my Nvidia graphics card drivers (320.49 beta drivers). I installed that and then completely reinstalled Arma 3 Beta.
Since then I have not had the crash but that was only a few days ago so I would like more time to truly test this in all scenarios.
