Attached to Project - sip-router Summary - tls module crash on initialization when used together with the dialog module Task Type - Bug Report Category - dialog Status - Assigned Assigned To - Timo Reimann Operating System - Linux Severity - Medium Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - I've tried to enable the tls module, but if the dialog module is loaded the tls module crash. If I disable the dialog module tls loads fine. Note that if «enable_tls» is «no» Kamailio doesn't crash.

Tested both on latest 3.2 and master branch. Built only with db_postgres and tls modules. Running on 32-bit RHEL 5.
