parsing API "z!" broken

hi,

I met a weird bug yesterday, using "z!" with unset variables works on
unix but fail on windows. For example:

PHP_FUNCTION(foo)
{
	char *a;
	int a_len;
	long b = 0;
	zval *authns = NULL, *addtl = NULL;

	if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|lz!z!", &a,
&a_len, &b, &c, &d) == FAILURE) {
		return;
	}


case 1:
foo("a", 1, $c, $d);


case 2:
$c = NULL;
$d = NULL;
foo("a", 1, $c, $d);

Case 1: c and d will be a NULL
Case 2: c and d will be valid zval ptr

I did not test yet under 5.3 linux but similar cases work well with 5.2.


Cheers,
