[AGENT++] valgrind reports invalid write in agentpp

[Jacquemin, Jean-Philippe]

Dear All,
 
 
I am running valgrind on my snmpagent and it finds errors in the V3 Mib.
 
==2171== Invalid write of size 4

After debugging I found out the problems come from the following piece
of code:
 
agentpp/src/v3_mib.cpp: 383
 
"
const Oidx UsmUserTable::auth_base = oidUsmAuthProtocolBase;
const Oidx UsmUserTable::priv_base = oidUsmPrivProtocolBase;
"
 
 
Has someone encountered this as well ?
What can be the solution ?
 
Best regards,
 
 
Jean-Philippe
