Sorry, it's basically all comments. Do you have the stdout from the subdriver script? Also, how is the MIB file installed?

^ Hmm, I thought we defaulted to CFLAGS=-g, but apparently it's CFLAGS=-O. Can you rebuild with "-g"?

Actually, using "-DDD" might provide enough extra context (there is an upsdebugx(3, ...) right before one of the snmp_parse_oid() calls). But debugging symbols would be good, too.

Almost there - we just need to know what called snmp_parse_oid(), and why the arguments were bad.
