Details - If a cr_route is called via PVs and the carrier pv is pointing to a non existing carrier, it segfaults.

from the config file:
xlog("L_INFO","[$mi] cr_route(\"$avp(i:707)\", \"$var(domain)\");\n");
if (cr_route("$avp(i:707)", "$var(domain)", "$rU", "$rU", "call_id")) {

And the logs shows:
INFO: <script>: [1] cr_route("3", "1"); 
ALERT: <core> [main.c:722]: child process 4152 exited by a signal 11 

There's no carrier 3 in my routes, but this should not crash the server.

Here's the backtrace:
