SNMPD crash in NET-SNMP-5.2.2 on x86.

Hello list, 
 
We are using NET-SNMP-5.2.2, and we have a subagent (linked with
NET-SNMP-5.2.2 libraries).  When the subagent closes the session, while
a Manager is walking on the MIBs supported by it, we are seeing SNMPD
crash.  Following is the stack trace of it.

(gdb)fr 0
(gdb) p *reginfo
Cannot access memory at address 0x14300101

 
I have a question about the reginfo.  Is this not gettig freed as part
of unregister_mibs_by_session(session); called from
close_agentx_session()?  By any chance, are we trying to free the
already freed memory? 
 
Any help in this regards would be gretly apreciated.  Please let me
know, where to upload the core? 
 
Regards
Mahesh
