report in the console window?

Do you use OpenCL to preview multiple subdivision levels?
Does it happpen when you are NOT in smooth preview mode?

I don't get any long error in the console. It's just saying "erl.exe has stopped working". It's the classic error window you get on Windows 7 when an app crashes.
The console is just displaying the text it always displays after starting wings.

I can reproduce it consistently. I'm not using opencl if it's not somehow enabled by default. Please let me know if I can provide any other information.

Please take a look at the attached screenshot. Is there something I can do to get a stacktrace or some more debugging output?

Edit: undoing after subdividing up to ~190.000 polygons seems to crash it most of the time. It might somehow be related to undoing.

Edit 2: toggling show edges / show backfaces seems to fix the issue sometimes. I'm not sure what's the problem. I'll try to record the screen, maybe that'll help.
