Bill and all,

This is really a bad stack trace. But if somebody has a dbx debugger
installed and can reproduce the problem:

Configure online with one cpu vp and then as root run:
dbx $INFORMIXDIR/bin/oninit
(dbx) run -d
where # run this after dbx reported a crash

I hope that this will give us a stack trace (which ususlly tells me a lot).
