Hi all:
I have some problem using net-snmp in multi-threads application.
my version of net_snmp is 5.5,(I have also tried 5.7.3).
the application is simple, which is much like snmpdemoapp.c in the
wiki, and use the Single Session API, with several threads, each has its
session and read some
information from remote host, I followed the advice in README.thread--,
invoke the snmp_sess_init() before adding task to each thread,but still get
wrong result.
most time it work well, but after I quit with Ctrl + C, then
restart,error occur, the output are as below:

if the failure is caused by data race, each run should fail as data race, is
that caused by file operation such as not clear before quit as Ctrl + C,any
advaice?
