Hit this again on turn 128 of a new game. The last line of the debug.err is "DebugMessage: Error allocating memory."
debug.err is here.
dxdiag is the same as in the OP.
I checked the Elemental folder in the Program Data directory and found a .dmp file and a 0 byte .zip file that have the same timestamp as my crash. So maybe it managed to get the dump but was killed before it could zip it?
The .dmp file is here.
