Knowledge of C is required to affirm or deny my statement.
Knowledge of programming is required to understand the gist
of what I am saying.

typedef int (*ptr)();  // ptr is pointer to int function
00 int H(ptr x, ptr x);
01 int D(ptr x)
02 {
03   int Halt_Status = H(x, x);
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 }

Any H/D pair matching the above template where
D(D) is simulated by the same H(D,D) that it calls
cannot possibly reach past its own line 03.
This is a simple software engineering verified fact.
