powmod via script gives me incorrect results when it starts using Generic modular reduction. I was learning using script en scriptify and started by making a Mersenne Prime script. It first checks the candidates by powmod base 3 and when it is successful it runs a complete test. It finds all the Mersenne primes up to 607 but for p>=647 modular reduction is used and incorrect results are generated. Is this a known bug or am I doing something wrong?
