Description:
------------
gmp_hamdist() continuously produces a crash:

if (ZEND_NUM_ARGS() != 2 || zend_get_parameters_ex(1, &a_arg, &b_arg) == FAILURE){

1 should be 2, b_arg is not being set properly, and thus FETCH_GMP_ZVAL(gmpnum_b, b_arg); is crashing.

Reproduce code:
---------------
<?php
    gmp_hamdist("1", "2");
?>

Actual result:
--------------

Fixed. (why didn't you fix this yourself..?)
