Summary 0001472: OutOfMemoryError with OCIFetchStatement
Description On using OCIFetchStatement in a php page that runs over quercus we receive an OutOfMemoryError exception: "java.lang.OutOfMemoryError: Java heap space"

We created a very simple case to reproduce this bug. See in additional info please.
Additional Information <?

function getConnection() {
    $db = OCILogon('user', 'pass', '//server:1521/ORCL');
    return $db;
}


$db = getConnection();

$curs = OCINewCursor($db);
$sql = OCIParse($db, 'BEGIN user.package.sp_xxxx(:return_cursor); END;');
OCIBindByName($sql, ':return_cursor', &$curs, -1, OCI_B_CURSOR);
OCIExecute($sql);
OCIExecute($curs);

$pes = array();
// !!! HERE THE PROBLEM OCCOURS !!!
OCIFetchStatement($curs, $pes);

 (rep by osmedd)

I developed a very short program that replicates the problem, it appears to be in the return from the oci_fetch_all() php call (it doesn't seem to get to the 'never get here' line when logging is added in). I don't see any references to the OracleModule in the stack trace, so I think I've gone about as far as I can go.

php file:
<?
$conn = oci_connect("USERID", "PASSWD", "java:com/env/jdbc/DB");
$stmt = oci_parse($conn, "select client_id, client_name from client where client_id = 'XYZZY' and client_status = 'A' order by client_name");
oci_execute($stmt);
$rows = oci_fetch_all($stmt, $oraresults);
// never get here...
if ($rows == 0) {
echo 'No results.';
}
else {
echo 'Got results!';
}
oci_free_statement($stmt);
?>

We are alive.
