If I change to snmp_close(), actually it won't core-dump, but I think that
is not right to do. Any thoughts?

I have a member function closeSession() and destructor that calls
closeSession()
void mySession::closeSession()
{
if(sessp != NULL && session_openned == true) {
snmp_sess_close(sessp);
sessp = NULL;
SOCK_CLEANUP; // probably should not be here
session_openned = false;
}
} // end closeSession
and
mySession::~mySession()
{
if( sessp != NULL && session_openned == true)
closeSession();
} // end ~Session
If I comment out the actions in destructor, the code runs fine. I don't
understand why. The core seems to yell on double free.

Hi,
I am using the signle session API for multi-threaded application. I am
calling SOCK_STARTUP and SOCK_CLEANUP from mainthread, the stack frame
shows:
(gdb) where
#0 0x402ed4f9 in free () from /lib/libc.so.6
#1 0x40065360 in snmp_free_session () from /usr/lib/libnetsnmp.so.5
#2 0x400654a4 in snmp_sess_close () from /usr/lib/libnetsnmp.so.5
anybody can give a hint what could be wrong.
Thank you.
