[SR-Users] userblacklist use avp for check_blacklist

[Jan Hazenberg]

I just tried to use the check_user_blacklist function but then kamailio 
crashed when i start it. I'm using the following code:


         if (!check_user_blacklist("blacklist", "$avp(from_domain)", 
"$(avp(ruri_number){s.substr,1,0})")) {
                 xlog("L_ALERT", "ALERT: $rU is blacklisted, rejecting 
call - IP=$si PORT=$sp R=$ru ID=$ci FU=$fu M=$rm UA=$ua\n");
                 sl_send_reply("403", "Forbidden");
                 exit;
         }

This is the GDB output:

Core was generated by `/usr/local/sbin/kamailio -P /var/run/kamailio.pid 
-m 768 -M 16 -u kamailio -g k'.
Program terminated with signal 11, Segmentation fault.
#0  0x00007fdf4b2be6fb in str2int (_s=0x7fff312b7bd0, _r=0x30) at 
../../parser/../parser/../ut.h:643
643             *_r = 0;


I have kamailio 4.4.0 installed, just tested with 4.4.1 and the result 
is the same.

Thanks,

Jan
