[Opendnssec-user] signed crash (1.3.4)

Morning everyone,

I had my two opendnssec instances crash on me tonight, under similar but
not identical circumstances. I'm curious if this rings a bell with
someone.... Both signer crashed on the same zome. They receive the same
input zone at the same time, use the same keys but are autonomous (by
managing their own signs, jitter,...).

The backup signer crashed with the zone export at 19:00 with this
message (in kernel log - nothing in its own logs):

ods-signerd[12413]: segfault at 7f4a00000022 ip 000000000041a97e sp
00007f4aad439da0 error 4 in ods-signerd[400000+3d000]

What we got out of this is:

addr2line -e /usr/local/opendnssec/sbin/ods-signerd 000000000041a97e
 -> /usr/local/src/opendnssec-1.3.4/signer/src/signer/rrsigs.c:170

in rrsigs_cleanup(rrsigs_type* rrsigs):
l170: if (rrsigs->next) {

The main signer dies with the following zone export, 4 hours later with

ods-signerd[13147] general protection ip:7f2be77a91e9 sp:7f2be44a1cc0
error:0 in libldns.so.1.6.9[7f2be7791000+4b000]

(no further information on this one)

As the did not crash on the same input file, I'd expect a problem with
renewing an expiring signature...

Anyone seen this before? Any ideas on the trigger (and even better: how
to prevent reocurrence)?
