A bug. php shouldn't die if a NULL is passed, it should give an
error as if you typed:
func('a', 'b', 'c');
An error should complain about passing constant to reference.
But, it is fixed with 4.3.3RC1. so no need to submit a bug on it:
<?php
function foo($a, $b, &$c) { }
foo('a', 'b', NULL);
?>
Results:
Fatal error: Only variables can be passed by reference in
/usr/home/www/domains/dyndns.org/web/zirzow/_/php/tests/bugs/func_ref_null.php
