I'm using stunnel4 in client mode on my laptop to let leafnode's
fetchnews access newsservers over SSL.
# egrep -v '^(;|$)' /etc/stunnel/stunnel.leafnode.conf
chroot = /var/lib/stunnel4/
setuid = stunnel4
setgid = stunnel4
pid = /stunnel4.leafnode.pid
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
debug = warning
syslog = yes
client = yes
[guinan]
connect = somehost:563
accept = localhost:563
[colleen]
connect = anotherhost:563
accept = localhost:564
And then /etc/news/leafnode/config contains:
server = localhost
port = 563
server = localhost
port = 564
As soon as fetchnews connects, stunnel4 segfaults.
Hm, no, according to strace, the first server works, and there's lots
of talk to the second, even including a QUIT and a Bye and then it
explodes:

The server is in both cases inn2{,-inews} 2.6.0-2+b1.
It seems that the problems are somehow related to openssl; and
stunnel4 3:5.37-1 is linked against openssl 1.1.0, stunnel4 3:5.36-1
against openssl 1.0.2. And with 3:5.36-1 I don't see any problems.
Cheers,
gregor
