Problem with RtConfig

Hello,

I would like to report a problem with regard to the latest version of 
RtConfig (v4.8.5)

We use RtConfig v4.7.1 for quite some time, without problems, in order 
to create our bgp filters (see as5408).
We recently tried to upgrade to v4.8.5. Unfortunately,  the newest 
version keeps crashing. The problem seems to occur whenever we use 
peering groups,
no matter how simple the RPSL is. This is an example that demonstrates 
the problem:

Step 1: We override RIPE objects AS5408 and prng-as5408-grnet-customers 
by defining them on a file named POL, with the following content:

ntua at nfc1~/RtConfig/>more POL
aut-num:        AS5408
as-name:        GR-NET
descr:          Greek Research & Technology Network
export:         to prng-as5408-grnet-customers announce ANY;
admin-c:        GN1931-RIPE
tech-c:         GN1931-RIPE
mnt-by:         GRNET-NOC
source:         RIPE
changed:        alioumis at noc.grnet.gr 20090209

peering-set:    prng-as5408-grnet-customers
descr:          GRNET (AS5408) Peering Group.
descr:          All GRNET customers
peering:        AS3323
tech-c:         GN1931-RIPE
admin-c:        GN1931-RIPE
mnt-by:         GRNET-NOC
changed:        A.Polyrakis at noc.ntua.gr 20040521
changed:        A.Polyrakis at noc.ntua.gr 20050210
changed:        A.Polyrakis at noc.ntua.gr 20050404
source:         RIPE
ntua at nfc1~/RtConfig/>

Step 2: We run RtConfig, using file POL, then we ask to create export 
policy for AS5408 for peering group prng-as5408-grnet-customers:

ntua at nfc1~/RtConfig/>/export/home/ntua/irrtoolset-4.8.5/bin/RtConfig -h 
whois.ripe.net -p 43 -protocol ripe -f POL
RtConfig> @RtConfig exportGroup AS5408 prng-as5408-grnet-customers
Warning: filter matches ANY/NOT ANY
!
no route-map MyMap_5408_1
!
route-map MyMap_5408_1 permit 1
exit
!
router bgp 5408
!
 neighbor PRNG-AS5408-GRNET-CUSTOMERS peer-group
 neighbor PRNG-AS5408-GRNET-CUSTOMERS route-map MyMap_5408_1 out
!
Assertion failed: 0, file ../../src/irr/autnum.hh, line 747
Abort (core dumped)

Please note that the same command on the older version of RtConfig succeeds:

ntua at nfc1~/RtConfig/>/export/home/ntua/RtConfig/RtConfig-4.7.1 -h 
whois.ripe.net -p 43 -protocol ripe -f POL
RtConfig> @RtConfig exportGroup AS5408 prng-as5408-grnet-customers
!
no route-map MyMap_5408_1
!
route-map MyMap_5408_1 permit 1
!
router bgp 5408
neighbor PRNG-AS5408-GRNET-CUSTOMERS peer-group
neighbor PRNG-AS5408-GRNET-CUSTOMERS route-map MyMap_5408_1 out
RtConfig> ^D


Any help would be greatly appreciated. Is there something wrong with our 
RPSL? Has anyone else encountered similar problems? Is there a know bug 
with regard to this issue?

Regards,
Andreas Polyrakis
