"use_socket: true" results in error "Recevived 0 instead of expected 1 bytes"

I faced the exact same problem as described here.
Running in a docker container, docker-compose.yml:

    php:
        build: php
        volumes:
          - ../app/backend:/var/www/symfony
    rabbitmq:
          build: rabbitmq
          privileged: true
          ports:
            - "5672:5672"
            - "15672:15672"
            - "15671:15671"
          environment:
            - RABBITMQ_DEFAULT_USER=root
            - RABBITMQ_DEFAULT_PASS=default
          expose:
            - 5672

Symfony config.yml:

old_sound_rabbit_mq:
    connections:
        default:
            host:     'rabbitmq'
            port:     5672
            user:     'root'
            password: 'default'
            vhost:    '/'
            lazy:     true
            connection_timeout: 60
            read_write_timeout: 60

            # requires php-amqplib v2.4.1+ and PHP5.4+
            keepalive: false

            # requires php-amqplib v2.4.1+
            heartbeat: 30

            #requires php_sockets.dll
            use_socket: true # default false
    producers:
        offline_sync:
            connection:       default
            exchange_options: {name: 'offline-sync', type: direct}
            enable_logger: true
    consumers:
        offline_sync:
            connection:       default
            exchange_options: {name: 'offline-sync', type: direct}
            queue_options:    {name: 'offline-sync'}
            callback:         app.test_handler
            enable_logger: true

Running:

php bin/console rabbitmq:consumer -w offline_sync

Sockets and mbstring extensions are installed.
Setting use_socket: false fixes the issue.
So isn't it a bug? Are we unable to use sockets?

Creators don't care. Closing.
