Yes, it is. It's an FC6 box running VMWare server, with a Win 2k3r2 VM
and a Vista ultimate VM, both with mingw and msvc animals.

I'm still not convinced it's a hardware problem - aside from the fact
that it's the same error every time (although, I note in this case it
was in check, not installcheck), I would expect at least one of SMART,
FC6, VMware or 2k3/Vista to spot that there was a problem. I have also
recreated the virtual disks of both VMs since this started happening. I
wonder if we're hitting some odd bug in VMware.

Anyhoo, unfortunately Baiji wasn't set to keep error builds - I've
changed that now and will run it a few times again. I'll also run a
sector level check of Narwhal's virtual disk and see if that complains.

Regards, Dave.
