behavior as the directly executed D(D) is for the instructions
of D to be incorrectly simulated by H (details provided below).

In order for D simulated by H to have the same behavior as the
directly executed D(D) H must ignore the instruction at machine
address [00000d07]. *That is an incorrect simulation of D*
H does not ignore that instruction and simulates itself simulating D.
The simulated H outputs its own execution trace of D.
