[Nut-upsuser] Arch Linux and Tripp Lite web snmp card issues.

I have been working with NUT to get this working since upgrading to a 
web snmp card in a UPS. I keep getting seg faults when running snmp-ups 
also. Below is the output.

kernel: [1365065.178230] snmp-ups[1940]: segfault at 0 ip b7555470 sp 
bf8d89e8 error 4 in libc-2.18.so[b74c2000+1a9000]

Running: Arch i686 current

Nut is current git

Device is Tripp Lite SU2200XLa with WEBSNMPCARD running version12.04.0055.

snmp-ups output:

That's not good. If you crank up the debug level past 2, does it provide any
more detail about where it crashed? (We'd only need the last few lines, if
they are different.)

I don't know how Arch Linux does debug symbols, so the dmesg output
doesn't pinpoint which function in libc got bad data. Can you run it in gdb
and get a backtrace? That will probably be something like this:

$ gdb snmp-ups
(gdb) run -a <UPS-name> -DD
...
(gdb) bt
> SNMP-Walk:
NUT ends up using the numeric OIDs internally. Could you please follow the steps
here:

http://www.networkupstools.org/docs/developer-guide.chunked/ar01s04.html#_creating_a_subdriver

Either "mode 1" or "mode 2" should work, but if you run into
trouble with "mode 1", just dump the files as mentioned in "mode
2", gzip them, and post them to the list. For the "-n" flag,
I'd recommend "trippups1", as that seems to be one of the more
common names for that MIB.

Thanks for the quick response Charles! I may not have gotten the correct 
output from the snmpwalk, let me know if the attachment is usable.  Thanks!

New data added, here is the gdb output:
Reading symbols from /usr/bin/snmp-ups...(no debugging symbols 
found)...done.
(gdb) run -a tripplite -DD
