# Bug using no-check in HAProxy backend

This seems to be a bug in the official Docker image for HAProxy. When
specifying no-check for a server, HAProxy segfaults.

I have prepared a test case, which is attached here. To run it:

$ docker-compose build
$ docker-compose up

I get:

haproxybug_haproxy-no-check-alpine_1 exited with code 139
haproxybug_haproxy-no-check_1 exited with code 139

## Tested using

Docker version 17.12.0-ce, build c97c6d6
docker-compose version 1.17.1, build 6d101fb
Host machine is running Ubuntu 16.04, kernel 4.4.0-112-generic

Images tested are haproxy:1.8 and haproxy:1.8-alpine.
