Description
Symfony version(s) affected: 4.1 (since 4.1.5 - previous not affected)
Description
When having a "complex" service graph consisting a mixture of constructor injection and setter injection, the dumped function in the container will attempt to use a variable before initializing it.
The container will error out with something like:
Notice: Undefined variable: b
How to reproduce
I tried to reduce the amount of involved services to the absolute minimum, this is how far I got it narrowed down.
The following unit test breaks the container dumper on my machine.
Reducing it more, like removing any of the ->addMethodCall() declarations or any of the arguments of multiuse1, will not exhibit the issue anymore.
