Just now tried out Snowstorm, version 184.108.40.206218, and watched it snarf down all available RAM and crash in minutes, just as Kirsten's client has been doing for me. The problem is, therefore, something common to them, or possibly something about my computer and what I'm running (which is now the Release Candidate of Ubuntu 10.10, using nVidia's latest beta Linux driver, 260.19.06).
UPDATE: What's the deal? When you want it to break, it doesn't! Ah, well, I think I now have two logs, one from a crash, one from a normal run. Maybe being able to compare will help.
