Description:
------------
Use of $result->num_rows in any case causes PHP/Apache crash.

Env:
Windows XP
Apache 2.0.48
MySQL 4.1.2 alpha
PHP RC2 (in previous releases the bug also existed)

php.ini:

zend.ze1_compatibility_mode = Off
allow_call_time_pass_reference = Off
error_reporting  =  E_ALL
register_argc_argv = Off
extension_dir = "./"

extension=php_mysqli.dll
extension=php_mysql.dll
extension=php_gd2.dll
extension=php_imap.dll

Reproduce code:
---------------
if($stmt = $sql->prepare('...')) {
    $stmt->bind_param('s', $s);
    $s = 'cat';
    $stmt->execute();

    $stmt->num_rows;
    OR
    if($stmt->num_rows > 0) {

In other words, any use of num_rows.


Expected result:
----------------
I expect that no crash will happen:)

Actual result:
--------------
Internal Server Error
