[AGENT++] Segmentation fault while finalizing request answer!

[Frank Fock]

Hi Carlos,

Most likely you hit a FAQ. When you get a seg. fault
and you changed some compiler settings before
(e.g. disabled _THREADS or SNMPv3) then in 99%
of all cases you have not made a clean compilation
of *all* your libraries.

Best regards,
Frank
