Thats encouraging (at least for my NetBSD/vax hacking) in that its not
just the VAX or me doing something insane.

If it is the same issue then vax may be helpful in that its an instant
SEGV on startup rather than odd behaviour some non-deterministic time
after start.

Its been a while since I poked at it - I'll try to dig back in again
and determine where its going bang to see if anything is obvious...
