DECIDERS ARE REQUIRED TO REPORT ON THE SEMANTIC OR SYNTACTIC PROPERTY OF
THEIR INPUT FINITE STRINGS.

And not if the input called a different simulator that didn't abort.

It hardly matters. Either his emulation faithfully and correctly establishes and reports (for EVERY program anyone cares to feed it) the actual halting behaviour exhibited by the program it's emulating, or it doesn't.

 Not a program, and can not be correctly emulated beyond address 0000217A as it goes outside the input.
 

In other words you are stupidly trying
to get away with saying that it is impossible
for one C function to call another C function.
