OSPF segfault

[1 Игорь]

Another thing, that i have discovered, is that every works normal if i set mtu 9000 on all interfaces between routers in area.
If config is needed, i attach it:
# Configure logging
#log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug };
log stderr all;
log "/var/log/bird.log" all;

filter OSPF_in {
        if ( net=0.0.0.0/0 || net ~ 10.0.0.0/8 ) then
                accept;
        else
                reject;
};

filter OSPF_out {
        if (net ~ 10.16.0.0/12 ) then
                accept;
        else
                reject;
};
