debug log with bbacktrace, 50894
Tested with VBox 4.0.4, rev 50894. To replicate, open a program in Olly and step through it and use menus from time to time. After 5-10 minutes of use (VM was assigned 512MB of ram), Olly's window gets corrupted, it crashes right afterwards, or when you try to close it. Debug log with backtrace attached.
