Attached to Project - sip-router Summary - segfault on loading dialplan module 3.1.1 Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - Linux Severity - High Priority - Normal Reported Version - 3.1 Due in Version - Undecided Due Date - Undecided Details - Version 3.1.1 segfaults on loading dialplan when loading a row with match_op 1. When the match mode was changed to 0 it works

To isolate the bug we loaded kamailio dialplan module with the very simple match_op 1 regex row in the database (Postgres) and took a backtrace of the segfault.

# select * from coreout_dialplan; id | dpid | pr | match_op | match_exp | match_len | subst_exp | repl_exp | attrs -----+------+----+----------+-----------+-----------+-----------+----------+------- 482 | 100 | 1 | 1 | ^201$ | 0 | | NJ |

Backtrace is below:
