What I remember I installed the net-snmp tools (www.net-snmp.org) and used one of the tools included
(e.g. snmptranslate) and maybe put the warning level up in net-snmp so that I could see exactly what mib that caused the problem and some details about what was problem with that MIB.

The crash information I got on Windows 98 looked like the one in this message:
http://www.ethereal.com/lists/ethereal-users/200212/msg00090.html

The crash occurred in the function find_tree_node. The backtrace looked something like this:

There was a message with more or less the same crash information in one of the messages on
NET-SNMP Sourcefourge bug-reports:
http://sourceforge.net/tracker/?atid=112694&group_id=12694&func=browse

It was there I could see the hint that you could get that specific problem if there was an IMPORT .... FROM missing in the MIB.
There is also a similar thing mentioned in the following discussion (see: 'you need to import "enterprises" FROM SNMPv2-SMI')
http://net-snmp.sourceforge.net/irc/net-snmp.log.2002-9-12.html

I'm not sure if they really have solved the problem in a later version of NET-SNMP.
