Description:
------------
Any call to a mysql stored procedure produces the following error:

"PROCEDURE database.store_proc_name can't return a result set in the given context"

When calling the stored procedure from mysql cli client do return the results correctly.

Tested against MySql 5.0 and 5.1.

Work on php-5.2.9 but not on php-5.3.0 or php-5.3.1


Reproduce code:
---------------
DELIMITER $$
CREATE PROCEDURE `myproc`()
BEGIN
SELECT 'it works!';
END$$

<?php
$link = mysql_connect('127.0.0.1','root','',false,65536);
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db('test', $link);
if (!$db_selected) {
    die ('Can\'t use maxdb : ' . mysql_error());
}
$query = 'CALL myproc();';
$result = mysql_query($query);
if (!$result) {
    $message  = 'Invalid query: ' . mysql_error() . "\n";
    $message .= 'Whole query: ' . $query;
    die($message);
}
$row = mysql_fetch_row($result);
var_dump($row);
mysql_free_result($result);
mysql_close($link);

Expected result:
----------------
array(1) {
  ["it works!"]=>
  string(9) "it works!"
}


Actual result:
--------------
Warning: mysql_query(): PROCEDURE test.myproc can't return a result set in the given context in /home/html/sp_test.php on line 11
Invalid query: PROCEDURE test.myproc can't return a result set in the given context
Whole query: CALL myproc();

Works with latest PHP 5.2, fails with 5.3+.
 [2010-01-04 10:51 UTC] uw@php.net 
This may be a valid error message, http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html . What's the code of the SP?
 [2010-01-05 14:53 UTC] ernesto_vargas at yahoo dot com 
@uw@php.net;

The store procedure code is a simple Hello World. Code is below.

DELIMITER $$
CREATE PROCEDURE `myproc`()
BEGIN
SELECT 'it works!';
END$$

Uwe, please notice my comment: It _works_ with PHP 5.2.x but NOT with 5.3, ergo, there's a bug in _PHP_ mysql stuff..
 [2010-01-12 21:11 UTC] ermesto_vargas at yahoo dot com 
Any ETA on when this issue will be review? 

jani@php.net have clearly assert that the error occur on PHP 5.3+

andrey@winnie:~/dev/php/PHP_5_3$ ./php a.php
string(6) "5.1.44"
array(1) {
  [0]=>
  string(9) "it works!"
}


This is a mysqlnd build, with libmysql I see the error message. This will be further investigated.
