Hello
When you compare 2 OIDs but the second is shorter by_oid returns
Use of uninitialized value in numeric comparison (<=>) at
/usr/share/perl5/SNMP/Extension/PassPersist.pm line 530, <STDIN> line

$v != 0 ... do not have to process whole @a the first difference makes
result
$#b == $i ... do not try to compare something vith nothing
it makes problems when using snmpwalk while any error output from script
makes snmpd restarting it.
