Unfortunately, by the time I saw Ruslan's message requesting the
buildworld output I had already built bsnmpd with the jZ malloc options
and now it just works. To get the failure again, I'd probably have to
roll my system back to Feb 23 again and then update and I just don't
have the time right now to do it. It's not a very fast system and
buildworld takes about 4 hours. It is also a remote system and I don't
have physical access to it until next Tuesday.

Sorry. Maybe someone else who stumbles over this can get a full
buildworld, but it probably only applies to people who built a system
from HEAD in the last week or so of February.
