I assume mills.cpp is your code? You pass three arguments to the mpz_powm function.

And the friendly compiler tells you that 4 arguments are required, which
also agrees with the GMP manual,
https://gmplib.org/manual/Integer-Exponentiation.html. What makes you
think this is a bug in the gmp library?

Questions on how to use gmp are best directed to gmp-discuss at gmplib.org.
