Sometimes PO accepts this a yes/no question with a correct answer in
every case and sometimes he does not.  On those days when he does accept
it, he asserts (quite unambiguously -- I can post a direct quote or a
message ID) that no is sometimes the correct answer even when P(X)
halts.

But on some days, PO does /not/ accept that there is a correct yes/no
answer to QA in every case.  On those days, he thinks there is a
"pathological input" for which there is no correct answer.

This was a very common problem with students.  They so buy into the
assumption "let H be a TM that decides halting" that they think that H'
and H^ (to use Linz's notation) also exist and so there really is a
concrete string of symbols (the encoding of H^ which I write as [H^])
such that H^([H^]) halts if it doesn't and doesn't halt if it does.

Of course, there are no pathological inputs like this because H does not
exist.  For every TM, M, the machines M' and M^ do indeed exist, [M^]
really is some finite string of symbols and M^([M^]) either halts or it
does not halt.  But because none of the infinite variety of Ms
implements the halting function, there is no paradox or pathological
input anywhere to be seen.

Aside...  Forgive me for repeatedly replying to you.  It's because I
know you from comp.lang.c and because you are, I think, new to this
thread which has been going on for over 20 years.  I think everyone else
here knows the history, but you might not know what PO has said in the
past and, anyway, I think it helps to remind everyone that PO has given
the game away more than once.

All the recent junk using x86 simulations was once very much clearer.
He posted a function:

u32 Halts(u32 P, u32 I)
{
 static u32* execution_trace;
 slave_state->EIP = P;                    // Function to invoke
 while (!Aborted)
 {
   u32 EIP = slave_state->EIP;            // Instruction to be executed
   DebugStep(master_state, slave_state);  // Execute this instruction
   PushBack(local_execution_trace_list, EIP);
   Aborted = Needs_To_Be_Aborted(execution_trace, (u32)Halts);
 }
 return 0;  // Does not halt
END_OF_CODE: // Input has normally terminated
 return 1;
}

and explained that 0 (does not halt) is the correct return for the
classic "confounding input" like so:

  "When we comment out the line of Halts() that tests for its need to
  abort then H_Hat() remains in infinite recursion, proving that its
  abort decision was correct."

All really clear: Halts is correct because it reports on what some other
program would do -- the H_Hat constructed from the modified Halts
function without the like that stops the simulation!

That was way too clear, so we got all more recent guff and, as far as I
know, he no loner ties to justify this ruse quite so explicitly.  His
argument is now that the simulation is correct right up until the point
when it isn't (as Mike Terry demonstrated quite explicitly).
