Question

Getting a segfault when trying to enable ssl on 1.5-dev17

Ubuntu Server 12.04

Tried almost every variation I could think of with private key and CA bundle concatenated and used as a single crt, also tried split crt with private key and ca-file as CA bundle.

/etc/haproxy/haproxy.cfg

global
   maxconn 4096
   daemon

defaults
   mode   http
   contimeout   5000
   clitimeout   50000
   srvtimeout   50000
   option forwardfor
   retries 3
   option redispatch
   option http-server-close

frontend http
   bind *:80
   reqadd X-Forwarded-Proto:\ http
   default_backend unicorn

frontend https
   bind *:443 ssl crt /path/to/private.key ca-file /path/to/bundle.crt
   reqadd X-Forwarded-Proto:\ https
   default_backend unicorn

backend unicorn
   server unicorn 127.0.0.1:8080 check

listen stats :8081
   mode http
   stats enable
   stats scope unicorn
   stats realm Haproxy\ Statistics
   stats uri /
   stats auth haproxy:YOURPASSWORDHERE

gdb output

Your configuration does not crash haproxy-1.5-dev17 for me. However, didn’t you by any chance do a first build without enabling ssl support, then only a partial rebuild with ssl ?
I mean, something like :

$ make TARGET=linux2628
...
$ make TARGET=linux2628 USE_STATIC_PCRE=1 USE_OPENSSL=1

If so, your build may be invalid, because some files requiring recompilation are not recompiled.

Could you try :

make TARGET=linux2628 USE_STATIC_PCRE=1 USE_OPENSSL=1 clean all
