Excellent question. I don't see anything in the code that would clear the
memory in the input session. Is ss NULL? If not, what does it contain for
community?
Whenever something really weird like this happens, my first thought is
'mismatched libraries.' Check that
ls /usr/lib/*snmp* /usr/local/lib/*snmp*
doesn't return multiple versions of the libraries. I'd also recommend building
a static version (configure --disable-shared --enable-static) for easier
debugging, and stepping into snmp_open and following it down the stack,
watching to see where the community gets cleared.
