Hello

I'd like to do some tests with the dialplan module, but Kamailio is crashing when it loads it. Actually the module is properly loaded if the table is empty, but it fails when a row is added; so I guess it's related with the way I've inserted the values. A core file is generated:

Core was generated by `./kamailio -f ../etc/kamailio/kamailio.cfg'.
Program terminated with signal 11, Segmentation fault.
#0  build_rule (values=0x0) at dp_db.c:439
439 new_rule->dpid = VAL_INT(values);
this looks a bit strange at first sight, 'values' parameter is NULL and should not happen. Besides that, in build_rule() functions there are other uses of 'values' before line 439, so the crash should have been earlier.

Please send full backtrace of the core, in gdb, run 'bt' command (or better 'bt full').

Also, if this reproducible, run:

./kamailio -f ../etc/kamailio/kamailio.cfg -E -dddd

and send the output.

Cheers,
Daniel

This is the relevant config:

#----- dialplan params ---
modparam("dialplan", "db_url", "mysql://xxxx:yyyyy@localhost/db")
modparam("dialplan", "table_name", "dialplan")
modparam("dialplan", "dpid_col", "dpid")
modparam("dialplan", "attrs_pvar", "$avp(s:dp_attrs)")

mysql> describe dialplan;

I'm probably making some stupid mistake...any clue?

Thanks in advance
