This system enables one C function to execute another C function
in debug step mode. When H simulates D it creates a separate process
context for D with its own memory, stack and virtual registers. H
is able to simulate D simulating itself, thus the only limit to
recursive simulations is RAM.

D correctly simulated by H cannot possibly reach its own line 09.

Is it dead obvious to everyone here when examining the execution
trace of lines 14 and 06 above that D correctly simulated by H cannot
possibly terminate normally by reaching its own line 09?

 Except that you fail to mention that you have admitted that you are NOT working on the Halting Problem, despite trying to use terminology similar to it, but having stipulated definition that are in conflict with computaiton theory.
 Note, "keeps repeating (unless aborted)" is a misleading statement, as your H will ALWAYS abort this input, and thus it NEVER will "Keep repeating".
 You don't like me pointing out the problem because you prefer to be able to LIE to people about what you are doing.
 You work has NOTHING to do with Halting, as your H/D are not even turing equivalenet to their namesakes in the proof you like to mention.

That is the exact verbatim post and the first respondent agreed
and immediately noticed that I was referring to the halting problem.
So I will go with what I said, you just don't know C very
well and want to keep that hidden behind rhetoric and denigration.
