Description:
------------
func_num_args is return a value arguments count.
count(func_get_args()) is same as func_num_args.
but when certain function has two arguments, an below result mismatched between func_num_args and count(func_get_args()).
when numbers of arguments are 2, this bug is caused.
above bug is caused on PHP5.0b4 too.


Reproduce code:
---------------
<?php
function certain_func(){
    $args = func_get_args();
    $argsCount = func_num_args();
    echo "func_num_args() returns $argsCount\n";
    echo "count(func_get_args()) returns ".count($args)."\n";
    echo "below list is an item of \$args :\n";
    print_r($args);
    echo "\n";
}

certain_func('one', 'two');
certain_func('one', 'two', 'three');
?>

Expected result:
----------------
func_num_args() returns 2
count(func_get_args()) retruns 3
below list is an item of $args :
Array ( [0] => one [1] => two [2] => )

func_num_args() returns 3
count(func_get_args()) retruns 3
below list is an item of $args :
Array ( [0] => one [1] => two [2] => three)
