[OpenSIPS-Devel] [opensips] dialplan causes crash on startup (#655)

Mon Sep 28 13:54:02 CEST 2015

I am running OpenSIPS 2.1 latest from git, and seeing a strange issue with dialplan module in conjunction with postgresql. Basically opensips will not start, even with an empty dialplan table and is terminated with a SIGBUS. 

The problem still happens with some rows in dialplan table, but disappears if I comment out dialplan module and call to dp_translate.

I have not tried to replicate with MySQL

OpenSIPs version is
