And you could have made that point without accompanying it by a long
article about various kinds of child abuse in a newsgroup that's
supposed to be about C.
You didn't have to let yourself be trolled.
I don't consider James' post to be trolling. But of course that inHowever, my point was that the common excuse of "I hate this crime so
much I lashed out" is not a valid excuse.

itself does not mean it is appropriate to reply here. However, I
replied to that post in the group (rather than email) because it seemed
to me that a point I had made previously needed clarification.
As has been pointed out by others, topicality in this thread was doomed
from the first post. I'd be happier if Olcott had never cross-posted
here, but we can't change that.
*spending countless messages on dodging the question*
For every H/D pair matching the following template where
H is a pure function:
Does any D correctly simulated by H reach its own line 06 and
halt or does the fact that D remains stuck in recursive simulation
prevent that?
typedef int (*ptr)(); // ptr is pointer to int function in C
00 int H(ptr p, ptr i);
01 int D(ptr p)
02 {
03 int Halt_Status = H(p, p);
04 if (Halt_Status)
05 HERE: goto HERE;
06 return Halt_Status;
07 }
08
09 int main()
10 {
11 H(D,D);
12 return 0;
13 }
It is trivial to see that for every H/D pair of the infinite
set of H/D pairs that match the above template that
D correctly simulated by H cannot possibly reach its own final
state at line 06 and halt because D correctly simulated by
H remains stuck in recursive simulation.
This provides the basis for simulating termination analyzer H to
correctly determine that the halting problem's counter-example
input D cannot possibly halt.
