If the ctarget line is not enabled, it reports:

1546-525 Object 0x20107DB8 is invalid or a libc heap object at line 535 in
../include/snmp_pp/address.h
1546-522 Traceback:
           d9e383fc = _debug_ufree + 0x38
           d9e30a18 = _debug_free + 0x18
           d9e213d0 = ? + 0x44
           1000b364 = __dt__10UdpAddressFv + 0x8C
           1000b24c = __dt__10GenAddressFv + 0xB0
           1000b0f0 = main + 0x78

And if ctarget is enabled, it reports:

1546-525 Object 0x20108468 is invalid or a libc heap object at line 535 in
../include/snmp_pp/address.h
1546-522 Traceback:

           1000b514 = __dt__10UdpAddressFv + 0x8C
           1000b3fc = __dt__10GenAddressFv + 0xB0
           1000b910 = __dt__10SnmpTargetFv + 0x74
           1000b2e4 = __dt__7CTargetFv + 0xB4
           1000b108 = main + 0x90
1546-525 Object 0x20108328 is invalid or a libc heap object at line 535 in

           1000b3fc = __dt__10GenAddressFv + 0xB0
           1000b120 = main + 0xA8

the snmp++ is linked as static lib.
