Symfony version(s) affected: 4.1.5

Description
Symfony DI is dumping the container in wrong order causing a Undefined variable b exception.

How to reproduce
I've created a gist containing the XML version of the entire container and the compiled PHP service that is causing the error:

In this gist you can see that the method calls is called before the service instantiation. (lines 16 and 20).
