OK, dug up the random seeds that are causing the system to reboot, and it
turns out that it's hard to reproduce the actual reboot, but in the cases
where it doesn't reboot it segfaults in the same code path that was
causing the other segfaults in this thread. So I think it's all the same
bug, although I can investigate further if needed.
