The first six steps of this mapping are when instructions
at the machine address range of [00000cfc] to [00000d06]
are simulated/executed.

After that the behavior of D correctly simulated by H diverges
from the behavior of D(D) because the call to H(D,D) by D
correctly simulated by H cannot possibly return to D.

When you put "V2" or "V3" or something similar on the subject line
you should tell what is different from the original version.

I provide 6 steps and then ask what are the next steps.
I provide all of the steps.

No params thus easier to see that it pushes its own machine address.

 My question is still unanswered.
 

When I answer the question that the difference
is that one of them had parameters and the other one
does not have parameters it is dishonest of you
to say that I did not answer the question.
