Description:
------------
count_chars() function converts the second argument ($mode) using 
convert_to_long_ex(). If $input and $mode are both a reference to 
the same variable, PHP crashs with a segfault.

Reproduce code:
---------------
<?php
$text = 'Hello World!';
$n = count_chars(&$text, &$text);
print_r($n);
?>
