Summary: core dump on Linux (net-snmp_5.0.8) in snmp_pdu_add_variable

Initial Comment:
On Linux ,With Net-Snmp-5.0.8, core dump occurs when 
snmp_pdu_add_variable() is called. 

The stack shows the core dump occurs 
1) During memove()  in snmp_set_var_objid() which is 
called by snmp_varlist_add_variable() which in turn is 
called by snmp_pdu_add_variable().
2) In other case, core dump occurs in malloc in 
snmp_varlist_add_variable() .

Both the above cases do not occur frequently.
The code apart from Net-Snmp have been reviewed and 
doesn't show anything that could lead to the problem 
above. Also the stack shows that core dump occurs 
when control is in snmp_cleint.c.

What can be the cause of the above problem?

Some memory corruption somewhere, or maybe a double free.
Have you tried running with a memory-debugger?
