Segfault when registering command bus

[szymach]

Hello,
I have tried registering your bundle like so:

prooph_service_bus:
    command_buses:
        command_bus: ~

while running my app on a Symfony3 web server with PHP 7.1. This has resulted in segfaults when attemping to use the console commands. The only clue I can give is that it was related to strtolower function and was fixed by changing the configuration to:

prooph_service_bus:
    command_buses:
        app_command_bus: ~ # <- a prefix

Segmentation faults are coming from PHP itself, not from this library. There is nothing I can do about it.
If you are able to create a reproducible script, you may submit this to the PHP bug list.
