Description:
------------
Data stored in MySQL 4.1 database as LONGBLOB object is fetched badly when prepared statement mechanism is used. Binded result is likely a heap of internal PHP data.

Reproduce code:
---------------
MySQL:

CREATE TABLE Upload (
  ID              INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
  Content         LONGBLOB NOT NULL,
  PRIMARY KEY (ID)
) Type=InnoDB CHARACTER SET 'latin1';


PHP:

- store some content (e.g. file) to table Upload

- fetch stored content via prepared statement:
...
$stmt = $conn->prepare('select Content from Upload where ID=?');
$stmt->bind_param('i',$id);
$stmt->execute();
$stmt->bind_result($Content1);
$stmt->fetch();
$stmt->close();
...

- compare stored and fetched content

Expected result:
----------------
Stored content.

Actual result:
--------------
Heap of internal PHP data.
