I was just testing some stuff out in the latest build of Doomsday (build 661) and I get an error message every time I exit Doomsday, which says "Application terminated due to exception - no RTTI data!"
I have a Windows 7 64-bit machine with an Intel 3000 graphics card.
This error message also screwed up my resolution and monitor display. Here is a screenshot of what happened.
Attached is a copy of my doomsday.out file.
