Bug description:using mysqli_stmt::send_long_data() makes execute() fail

Description:
------------
This bug was found from a framework test units after a system upgrade
(ubuntu/10.04 -> ubuntu/10.10). The bug was tracked that the
send_long_data() stopped working completely. If I try to use it for large
packets, the following execute() command will fail with error "Error
executing prepared statement. Incorrect arguments to mysqld_stmt_execute".

I made a script that reproduces 100% the bug and I ran it at 
ubuntu/10.04(php5.3.2, mysql5.1.41) PASS,
ubuntu/10.10(php5.3.3, mysql5.1.49) FAIL,
debian/squeeze(php5.3.3, mysql5.1.49) FAIL.

So I assume its a regression at php's 5.3.3.

Test script:
---------------
//Full test @ http://codepad.org/eKnJnWnC 

// Code chunk that trigger the problem.
if (!$stmt->bind_param('b', $null))
	die("Error binding parameters. {$stmt->error}\n");
foreach(str_split($big_data, $max_allowed_packet) as $packet )
	if (!$stmt->send_long_data(0, $packet))
		die("Error sending long packet. {$stmt->error}\n");
if (!$stmt->execute())
	die("Error executing prepared statement. {$stmt->error}\n");

Expected result:
----------------
OK: Executed prepared statement with blob less than max_allowed_packet.
OK: Executed prepared statement with blob bigger than max_allowed_packet,
sent at chunks.


Actual result:
--------------
OK: Executed prepared statement with blob less than max_allowed_packet.
Error executing prepared statement. Incorrect arguments to
mysqld_stmt_execute
