Can't afford?  As in financially?  There are multiple free
virtualization 
mechanisms out there and the OS images are free.  Setting up a clean vm
on your 
existing machine is trivial and takes about 30 minutes, tops.

In my current situation I cannot afford to set up a test box and try to
compile 
the snapshot from php.net. However, I will do so as soon as I can. In
the 
meantime here is the source-archive with all patches that I use, from
the Ubuntu 
Repositories: 
http://archive.ubuntu.com/ubuntu/pool/main/p/php5/php5_5.3.2.orig.tar.gz

Also, I can confirm that the same problem exists on an x64 box with the
same 
software versions too. All other requested information (schema,
versions) are 
provided in detail on the link in the description.

Please use a recent snapshot from our site, we don't know what kind of
patches Ubuntu applies. Please provide the table schema and data you are
querying. Whcih MySQL server version?

I am using the php5 package from the Ubuntu Linux APT repository. It
seems to use 
libmysql. And yes, mysqli is also affected.

Do you use mysqlnd with ext/mysql or libmysql, in either case does it
solve switching the lib?

Is mysqli affected by this issue too on your machine?

Description:
------------
A MySQL query that should return 5 records returns an infinite number of
records. 
It returns the 5 five records correctly, but then it returns them again,
and 
again, and again... Other SELECT statements are fine, this is the only 
problematic one. Also, this query works from the MySQL console just
fine. At 
first I thought it is an issue with Zend Framework but it turned out it
is 
probably not. See this url for (much) more info (also detailed
information to 
reproduce): http://framework.zend.com/issues/browse/ZF-9982

Test script:
---------------
$c = mysql_connect('host', 'user', 'pass');
mysql_select_db('db', $c);
$raw = mysql_query('SELECT name, level, parent FROM
allresources_view ORDER BY level ASC');
while ($r = mysql_fetch_assoc($raw)) {
var_dump($r);
echo '<br /><br />';
}
mysql_close($c);

Expected result:
----------------
5 records should have been returned from the database.

Actual result:
--------------
An infinite number of records are returned from the database.
