It doesn't happen all the time, but when it does (about 1 in 10 tries) it produces the C++ "abnormal program termination" dialog without the chance to send a message to poor old Erik who has to read all the Customer Error Reports.

Happens in 3D views and in plan, with shadows on and off. The 3D views tend to be a more likely victim of crashes during printing.

Doesn't happen when printing to other drivers.
