hmm, I see, same body alias...

Well, remove_unreachable_nodes does two things, it removes nodes that are
completely unreachable and also removes definitions of nodes where definition
is not needed, but they are still referenced and thus needs to stay.  I suppose
it is what happens here.
I will check how to silence the verifier.
