Every sufficiently competent C programmer knows

typedef void (*ptr)();
int HHH(ptr P);
void Infinite_Loop()
{
   HERE: goto HERE;
   return;
}
void Infinite_Recursion()
{
   Infinite_Recursion();
   return;
}
void DDD()
{
   HHH(DDD);
   return;
}
int DD()
{
   int Halt_Status = HHH(DD);
   if (Halt_Status)
     HERE: goto HERE;
   return Halt_Status;
}
That when HHH correctly emulates N steps of the
above functions that none of these functions can
possibly reach their own "return" instruction
and terminate normally.
Since HHH does see that same pattern that competent
C programmers see it correctly aborts its emulation
and rejects these inputs as non terminating.
