[stunnel-users] Segfault in stunnel

[Miroslaw Pietrzyk]

Hi,
 I have a problem with one of the stunnel installation (debian7). After some time of operation automatically turns itself off with the message:
(...)
Apr 24 21:03:45 routerpri kernel: [177332.400502] stunnel[34426]: segfault at 0 ip 00007f1f99ca9e20 sp 00007f1f99c16c68 error 4 in stunnel[7f1f99c94000+24000]

stunnel 5.15 on x86_64-unknown-linux-gnu platform
Compiled/running with OpenSSL 1.0.1e 11 Feb 2013

stunnel.conf:
pid = /var/run/stunnel.pid
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
debug = 7
output = /var/log/stunnel.log
syslog = yes
client = no
fips = no
verify = 0
CAfile = /etc/stunnel/SubCA2.crt
CRLfile = /etc/stunnel/SubCA2_CRL.pem

[service_1]
accept = 192.168.1.10:1000
connect = 192.168.1.10:1234
cert = /etc/stunnel/cert1.crt
key = /etc/stunnel/cert1_key.pem
ciphers = HIGH:!SSLv2:!ADH:!Exp:!aNULL:!eNULL:!NULL
sslVersion = TLSv1.2

When I use the lower level of encryption for example SSLv3, problem occurs after a longer period of normal operation. 
I will only add that the problem has also appeared on the previous version 4.54, which I was updating to the newest. Do you have any idea what could be causing the problem. 

Regards 
Mirek
