Works perfectly fine here.
But doesn't output any results, of course, since there is no "dummy"
table with "dummy" field.

Description:
------------
It appears the PDO execute is hanging when a MySQL stored procedure is
called. The same code works fine on PHP 5.1.2 & MySQL 4.0.21.  Once we
upgraded to 5.1.4, the problem began.  It looks as if the call is being
executed a couple of times in the MySQL queries.log.  Our application
code has many such calls and after attempting to execute each one the
browser eventually timesout.

When I subtitute the SQL statment in the prepare, it comes back fine.

Reproduce code:
---------------
create procedure pdo_test() begin select dummy from dummy; end;


$pdo = new PDO("mysql:host=localhost;dbname=x","x","x");
$stmt = $pdo->prepare("call pdo_test()"/*"select dummy from
dummy;"*/);
$stmt->execute();
echo "<B>outputting...</B><BR>";
while ($rs = $stmt->fetch(PDO::FETCH_OBJ)) {
	echo "output: ".$rs->dummy."<BR>";
}
echo "<BR><B>".date("r")."</B>";

Expected result:
----------------
should get 

outputting...
output: 1

Actual result:
--------------
timeout
