Hello,
we have a server with some config running an old version (1.4.25-1) of
haproxy under Debian wheezy. The reason we've not updated it is that any
new versions we had access to would crash.
Today I was able to pinpoint where the problem lies:
# haproxy -c -f /etc/haproxy/haproxy2.cfg
Segmentation fault
# haproxy -v
HA-Proxy version 1.5.8 2014/10/31
Copyright 2000-2014 Willy Tarreau <w@1wt.eu>
# cat /etc/haproxy/haproxy2.cfg
frontend public0
disabled #->varnish
bind 192.168.1.1:80
option httplog
option forwardfor
option httpclose
default_backend farm0
That config file is derived from the original config file (which worked
with older haproxy versions (<=1.4.25)) by removing stuff from it and by
replacing the IP address.
Here's the stack trace:
