Description:
------------
I got these errors while trying to inputing string to LOB using LOB's method save(); :

Warning: save() [function.save.html]: OCILobWrite: OCI_INVALID_HANDLE in /www/sample.php on line 15

Warning: load() [function.load.html]: OCILobGetLength: OCI_INVALID_HANDLE in /www/sample.php on line 19

This was tested with:
4.3.1-win32
4.3.1-linux
Latest snapshot on Linux.

Note: in oracle function there is in/out parameter used.
Additional exception from Oracle: ORA-22275: invalid LOB locator specified.

Reproduce code:
---------------
    //logging in
	$conn = OCILogon('user', 'pass', 'srvname');
    //creating new LOB locator
	$clob = OCINewDescriptor($conn, OCI_D_LOB);
	$sql = 'begin :ret:=test(lob_object=>:lob_object_param); end;';
    //parsing query - ok
	$stmt = OCIParse($conn, $sql);
    //binding variables - ok
	OCIBindByName($stmt, ':lob_object_param', &$clob, -1, OCI_B_CLOB);
	OCIDefineByName($stmt, ':lob_object_param', $clob, OCI_B_CLOB);
	OCIBindByName($stmt, ':ret', $return, 4);
	OCIExecute($stmt, OCI_DEFAULT);
    
	if($clob->save($param)) { // Warning: OCILobWrite: OCI_INVALID_HANDLE in sample.php on line 15
		OCICommit($conn);     // this warning appears only when using method save(); of LOB locator
	}
	
	print $clob->load(); // Warning: OCILobGetLength: OCI_INVALID_HANDLE in sample.php on line 19
	                     // when using load method in LOB locator
	$clob->free();
	OCIFreeStatement($stmt);

Expected result:
----------------
I'm trying to save string as CLOB using Oracle function.
I do expect it to work fine =)
Maybe I'm doing something extremely wrong?
If so, please, correct me.

Thanx in advance.
