That code is not from the mentined trace file. In that file _DDD()

at the address is executed (because that address points to the last

I had to make a few more examples such as HH1(DD,DD)

AFACT HH1 is the same as HH0, right? What happens when HH1 tries to
simulate a function DD1 that only calls HH1?

 I am going to have to go through my code and standardize my names.
H(P,P) was the original name. Then I had to make a one parameter
version, a version that is identical to H, except P does not call
it and then versions using different algorithms. People have never
been able to understand the different algorithm.
 typedef void (*ptr)();
typedef int (*ptr2)();
int  HH(ptr2 P, ptr2 I); // used with int D(ptr2 P) that calls HH
int HH1(ptr2 P, ptr2 I); // used with int D(ptr2 P) that calls HH
int  HHH(ptr P);         // used with void DDD() that calls HHH
int HHH1(ptr P);         // used with void DDD() that calls HHH
 *The different algorithm version has been deprecated*
int  H(ptr2 , ptr2 I);  // used with int D(ptr2 P) that calls H
int H1(ptr2 P, ptr2 I); // used with int D(ptr2 P) that calls H
 *It is much easier for people to see the infinite recursion*

Twice is not equal to infinitely. When will you see that?
It is strange that you call that an infinite recursion, when H aborts after two cycles and the simulated H cannot reach its own abort operation, because it is aborted when it had only one more cycle to go.
None of the aborted simulations would cycle more than twice, so infinite recursion is not seen for an H that aborts the simulation of itself.
