Well, if you have the CVS version, you have the version I'm
using. There is a couple minor changes to some test scripts that
aren't checked in (ucd_* scripts because the net-snmp command line
changed), but no other changes besides some debugging output ('cout <<
' lines). I'm still having DB problems occasionally (which I think are
ppc thread related at this point). But when I don't get those
problems, it's working fine (i.e. no seg-faults). 

If you haven't tried this yet, you might try doing a 'make clean;
make' in the top directory. Sometimes, minor recompiles mess up
inter-dependencies and the entire source needs to be recompiled. If I
remember correctly, a symptom of this is seg-faulting.
