sql query in post-auth - segmentation fault

[Mohamed Imran (NBI)]

Hi,

Having configured FR to talk to our MS SQL server which appears to work fine
now (radius -X doesn't complain anymore), I've tried a quick test, a very
basic condition to lookup a mac and update reply with a particular VLAN tag
if its exists..  and added the following in the post-auth section of the
default site.
- - - - - - 
post-auth {
 	- - - - -
	- - - - - 
	#
	sql
	if("%{sql:SELECT COUNT(*) FROM tblwindows WHERE MacAddress
='%{Calling-Station-ID}'}" ==1){
	update reply {
        		Tunnel-Type = VLAN
                	Tunnel-Medium-Type = IEEE-802
                	Tunnel-Private-Group-Id = 100
        	}
        	else {
        	update reply {
        		Tunnel-Type = VLAN
                	Tunnel-Medium-Type = IEEE-802
                	Tunnel-Private-Group-Id = 101
              	 }
        	         }
       	 }


radiusd -X reports a segmentation fault:

Segmentation fault

This same sql statement worked fine when I was initially playing around with
this and it worked ok against a MySql DB (FR version 2.2.x).

Ive also tried the same query against our MSSql server using isql on the
same server and that works fine.

What am I missing/doing wroing?
