Hello,

We have been using BIRD 1.6.3 on Ubuntu 16.04 as Route Server for a long time.

Recently we decided to implement a ROA check filtration but we're experiencing the daemon is crashing whenever
removing roa table from the file config even when the roa table is not applied anywhere.

In simple words: The ROA table is only defined in the config.

Here is а specific example:

root@rs2-lab:/usr/local/bird-new/etc# cat roa.conf

roa table r65501 {

    roa 1.2.3.0/24 max 32 as 65501;

}

#################################

Here is our simple bird config:

root@rs2-lab:/usr/local/bird-new/etc# cat bird.conf
log "/var/log/bird.log" all;
log syslog all;

debug protocols { events };
router id 10.10.10.100;
define myas = 12345;
protocol device {}

include "roa.conf";

#################################

So when I remove/comment "roa.conf" from the config - bird process is crashing

root@rs2-lab:/usr/local/bird-new/etc# birdc c
BIRD 1.6.3 ready.
Connection closed by server

Here is dmesg with the crash info:

Could someone BIRD developer can help on this issue? 

Thanks in advance!
