Hi,
Seems there are some serious problems with db_perlvdb. It gives segmentation fault as soon as i set it as db url for any module e.g. acc, sip_trace, msilo and so on.
Here is back-trace of core dump,

Hi,
I am trying to load db_perlvdb.so module using latest Kamailio branch v5.0.6 with git revision 49bd81ad7856dac9b2efd53597fb1c182de7440b on Debian Wheezy 32bit. The compilation and installation went successful however the module gives following error.

I tried to find module perl.so in modules folder of kamailio installation but there is none. Then i looked through the source code but no success.
After some googling, i found following link which states that perl.so was remained to app_perl.so since v4.x.
I have created a small patch for db_perlvdb.c which corrects this error.

Kindly update Kamailio master and branch trunks.
Thank you.
