This seems to regularly happen. I'll mixdown a project - 16bit, 44Hz, power1 dither - and I'll come back only to find crash reported in rdas1117.dll - ie, Roland Quad driver.
 
When it doesn't crash and I'll save the project after mixing down, I sometimes get crashes to the desktop. On other occasions, I'll close the project and get crashes to the desktop. 
 
Anyone?

Latest system update and driver here:

Also update your chipset drivers on Intel driver update website and your motherboards BIOS.

Thanks...I've had this version for the Quad for ages.
 
Also everything is up to date...ta anyways.

You might try ruling out a dodgy plugin but right now it points to the driver for some.reason as you say.
