I have had this CTD many times (six-ish) now and it always seems to be caused by the same activity. When I am fairly zoomed in to the world map and using the left click & drag to move the map around. "Throwing" the map, or trying to move it too quickly, cause one stutter in all the sound, then the game hangs for about a second, then CTD.
Here is the debug.err for a second crash with the same circumstances.
Here is the memory dump for that crash
