VBox 2.2.4 segfaults after heavy I/O => Fixed in 3.0

I get regular segfaults when running VirtualBox 2.2.4 or 2.2.2 PUEL on Ubuntu 9.04 amd64, with guest OS FreeBSD 7-STABLE amd64. The dmesg shows:
The segfaults occur while performing heavy I/O on 8 raw disks attached via AHCI. The heavy I/O originates from a ZFS RAID-Z ("RAID5") configuration on those 8 disks, and performing a scrub on the volume, which is 100% disk bound and takes little over an hour to complete. But often the crash is triggered within the first run, between 30-50 minutes.
On the third try, i tried to run a backtrace and dump. Logs attached, but the dump is over 1.7GB. I could try reducing the memory to reduce the dumpsize, but ZFS likes to use lots of memory so this could be problematic. I've already tried 5-passes with Memtest86+ so memory corruption is not an issue here. I think these crashes are a defect of Virtualbox, and would like help to debug this thing.
Kind regards, sub
