segmentation error while using mpz_powm in a loop

without a complete code we cannot reproduce your problem. I suggest you try
to print the values of your variables before the mpz_powm call, with say
gmp_printf. If you still get a segmentation fault *inside* the mpz_powm call,
please send your complete program to the list.
