[OpenSIPS-Users] Segfault on mi reload_routes

[Mark Farmer]

Hi all

I've seen reports of this elsewhere but didn't find a solution. When I use
opensips-cli to do a 'mi reload_routes' OpenSIPS segfaults.

I did a git pull and install clean yesterday on opensips-cli.

opensips -V

Oddly, it doesn't seem to matter what is in the last line, it errors
regardless but this is the part of the route that seems to trigger it:

else if (isflagset(Voicemail)) {
                $var(rtpflags) ="replace-session-connection replace-origin
trust-address force symmetric in-face=external out-face=internal";
                xlog("CUSTOM_LOG: Call goes to Voicemail service - Route to
Asterisk.");
                xlog("CUSTOM_LOG: Engaging rtpengine_offer with flags:
$var(rtpflags)");
                rtpengine_offer($var(rtpflags));
                xlog("CUSTOM_LOG: Rewriting host:port");
                rewritehostport("10.150.50.53:5060");
                force_send_socket(udp:10.150.50.51);
                return(1);
