Description of problem:
I am testing and configuring racoon as xauth_rsa_server with mutliple IP Pools provided to VPN clients based on ldap group authentication. In my configuration, there are two "mode_cfg" pools configured:

mode_cfg {
        auth_source radius;
        auth_groups "Domain Users";
        group_source ldap;
        accounting none;
        network4 192.168.241.5;
        pool_size 20;
        netmask4 255.255.255.0;
        conf_source local;
        dns4 172.16.0.1;
        #wins4 172.16.0.1;
        banner "/etc/racoon/motd2";
        split_network include 172.16.1.0/24;
}

# Users Pool
mode_cfg {
        auth_source radius;
        auth_groups "Domain Admins";
        group_source ldap;
        accounting none;
        network4 192.168.240.5;
        pool_size 20;
        netmask4 255.255.255.0;
        conf_source local;
        dns4 172.30.0.1;
        default_domain "example.com";
        wins4 172.30.0.1;
        banner "/etc/racoon/motd1";
        split_network include 172.16.0.0/12;
} 

and when I try to connect to this VPN server, racoon segfaults.

I am using rebuilded src.rpm package from rawhide - ipsec-tools-0.8.0-3.fc17.src.rpm with included LDAP and RADIUS XAUTH support.

How reproducible:
always

Steps to Reproduce:
1.configure racoon with multiple mode_cfg sections
2.start racoon and try to connect with ipsec client
  
Actual results:
racoon segfaults:
Jan 20 17:57:35 vpn-server kernel: : racoon[26321]: segfault at 7f64d293a000 ip 00007f64d26ee233 sp 00007fff47bc0440 error 4 in racoon[7f64d2688000+9e000] 

Expected results:
racoon continue accepting and finishing VPN connection from client

after segfaulting is VPN connection timed out. If I commented out ONE of two mode_cfg sections (nothing else changed inside configuration), VPN connection will be successfuly initiated and working. But with two sections, racoon always segaults. 
I have tried to change auth_source from radius to ldap (because ldap auth also works), but the behavior is same - segault for more than one mode_cfg section configured.
