Description:
------------
The problem is to insert or update CLOB fields in Oracle. When i use Bind variables with OCI library, i connect, parse and bind by name ok, but OCIExecute says that the LOB Locator is invalid. I search internet for several days and i've not find any solution. The code is equal to the php examles of the manual. I prove to pass the OCI-Lob object returned by OCINewDescriptor, to the OCIBindByName by the deprecated reference format and without reference, but the problem is the same. I suspect OCIBindByName modify the OCI-Lob object.

-------
Modules:
oci8 and several commons like mysql, gd, pgsql, sessions, etc.

------
php.ini

error_reporting = 2047

to reporting all errors



Reproduce code:
---------------
<?php
if ( !$conn = OCILogon("user", "pass", "base") )
	die "Conection failed.";

$SQL = "UPDATE table SET field = :var WHERE ID = 1";

if ( !($stat = OCIParse ( $conn, $SQL )) )
	echo "OciParse failed.<br />";

$lob = OCINewDescriptor($conn, OCI_D_LOB);

OCIBindByName($stat, ':PEPE', &$lob, -1, OCI_B_CLOB);

OCIExecute($stat);

$large_text = "realy large text...";

if( $lob->save($large_text) ){
	OCICommit($conn);
	echo "Blob successfully uploaded\n";
} else {
	echo "Couldn't upload Blob\n";
}

OCIFreeStatement($stat);
OCILogoff($conn);
?>

Expected result:
----------------
I espect to record the content of the variable $large_text (containing a large text) in the field "field" in the table "table".

Actual result:
--------------
Two warnings:

1 - In OCIExecute line php warning:

"Warning: ociexecute(): OCIStmtExecute: ORA-22275: invalid LOB locator specified in "this file" on line "OCIExecute line"


2 - In the last "if" line, when execute the save method, warning:

"Warning: save(): OCILobWrite: OCI_INVALID_HANDLE in "this file" on line "that line"

And no any changes in database. I can't record anything  :(
