I'm running 3.0.12 (AMD64 build) on Mandriva 2009.1 64bit, running a 32bit Windows XP guest. I recently needed to kick off a compile of my company's software (haven't had to for some time), and find that about 2/3rds of the way through VirtualBox crashed - the log showed a GURU_MEDITATION message. At this time I was running 3.0.8. I restarted, tried again, and got a crash again, though in a different spot. I decided then to upgrade this morning to 3.0.12 just in case there was something there related (changelog didn't show anything obvious) - but trying the build again resulted in another crash. In all the above tests my guest was running in seamless mode. For some strange reason I decided to switch out of seamless mode and try it. So after a restart of the guest (seamless doesn't go in and out smoothly on my system - but that's another issue) I kicked of the build again. Now it's working - the build completes without crashing. So I don't know why seamless would make a difference - or if something else in the environment has magically changed and seamless is a red herring. I've attached: VBox-crash-3.0.8.log - which is the log from the first crash in 3.0.8 VBox-crash-3.0.12.log - which is the log from the crash in my first attempt in 3.0.12 " defect closed other VirtualBox 3.0.12 duplicate Windows Linux
