All simulating termination analyzers are required
to predict what the behavior would be when the
emulation is unlimited (never aborted) otherwise
they could never report on the behavior of this function:

void Infinite_Loop()
{
   HERE: goto HERE;
}

Also something that you consistently ignore is that
HHH is not reporting on its own behavior. HHH is only
predicting whether or not an unlimited emulation of
DDD would reach the "return" instruction of DDD.

void DDD()
{
   HHH(DDD);
   return;
}
