Operating system: FreeBSD

PHP Bug Type: Reproducible crash
Bug description: gmp_hamdist() produces crash
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:
--------------
#0 0x0807c987 in zif_gmp_hamdist (ht=2, return_value=0x81c3994,
this_ptr=0x0, return_value_used=1)
