I'm having troubles getting net/net-snmp working on 5.2-RELEASE -- I've
tried both 5.1 and 5.0.9, and both are exhibiting the same behaviour. This
is with 5.0.9 (communities changed to protect the innocent):
newhost# snmpd -d -D -f -L

The debugging output of 5.1 is much, much more verbose, but still exhibits
the same quit-without-error-nor-coredump behaviour. The querying host
doesn't ever get any response.
(Flag order seems to be important -- this one actually /did/ fork from the
shell.)
And a similar run from 5.1:
newhost# snmpd -d -DALL -Lo -f
<snip very verbose debugging>
