Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Running the script from command line seems to work fine.
Apache version is 2.0.59 I'll trying an upgrade.

Description:
------------
Unable to read BLOBs from a given table and insert on another one,
because php hangs up after inserting the first record on destination
table.
Reproduce code:
---------------
SQL:
CREATE TABLE TBL_BLOB (id NUMBER(10), data BLOB);
CREATE TABLE TBL_BLOB2 (id NUMBER(10), data BLOB);
You will need to insert some records on TBL_BLOB.
PHP:
try {
$oPDO = new PDO($sDSN, $sUserName, $sPassword);
$oPDO->beginTransaction();
$sSQLRead = 'SELECT ID, DATA FROM TBL_BLOB';
$oStmtRead = $oPDO->prepare($sSQLRead);
$oStmtRead->execute();
$sSQLWrite = 'INSERT INTO TBL_BLOB2 (ID, DATA) VALUES (:id,
EMPTY_BLOB()) RETURNING DATA INTO :stream';
$oStmtWrite = $oPDO->prepare($sSQLWrite);
while (($aRow = $oStmtRead->fetch())) {
$iID = $aRow['ID'];
$rData = $aRow['DATA'];
if (is_resource($rData)) {
$sData = stream_get_contents($rData);
fclose($rData);
} else {
throw new Exception('Error fetching stream');
}
$oStmtWrite->bindParam(':id', $iID);
$oStmtWrite->bindParam(':stream', $resource, PDO::PARAM_LOB);
$oStmtWrite->execute();
if (is_resource($resource)) {
fwrite($resource, $sData);
fclose($resource);
} else {
throw new Exception('Error fetching stream');
}
}
$oStmtRead->closeCursor();
$oPDO->commit();
} catch (Exception $oE) {
$oPDO->rollBack();
throw $oE;
}
$oPDO = null;
Expected result:
----------------
No output, but TBL_BLOB2 should have same records from TBL_BLOB.
Actual result:
--------------
Apache hangs up, the page keeps loading forever.
Simply trying to debug the script I see no error, the script finishes
normally, but Apache does not send any response.
Uncommenting the fclose(<stream>) command then debugging, the debugger
stops after writing to TBL_BLOB2 on the second record.
