Description:
------------
When I try to do a oci_fetch_array with OCI_RETURN_LOBS in the  mode string the page hangs indefinitely.  No errors are produced but the page never even times out.  

OCI version is 1.2.3 from PECL


Reproduce code:
---------------
<?php

$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST=1.1.1.1)(PORT = 1521)))(CONNECT_DATA=(SID=FESTPROD)))";

$usr = "notreal";
$pwd = "itsfake";

$connection = oci_connect($usr, $pwd,$db);

$query = "SELECT * from CATEGORY where category_id=1111";

$statement = oci_parse($connection, $query);
oci_execute($statement);

while ($row = oci_fetch_array($statement, (OCI_ASSOC+OCI_RETURN_LOBS))) {
   echo $row['COMPLETE_RULES']."<br>";  //this will output LOB's content
}
?>

Expected result:
----------------
Lots of words ..........


.....end of words<br>

Actual result:
--------------
Page hangs
