Crash in memory allocator, try launching Arma with -malloc=system
Are you using a USB Headset?

Yes, two different USB Headsets in fact.
Further testing shows: the crash is only triggered if my telephony headset (plantronics DA80, mono) ist the default sound device.
Logitech G533 works fine.
-malloc=system fixes the crash as well
