insert into lobtest (lobdata) values('data data data data data data data
data');

php:
error_reporting(E_ALL);
//oci_internal_debug(1);
// uncommenting above shows the script crashes at
// OCILobRead2 at (ext\oci8\oci8_lob.c:242)
// introduced in the fix for bug #36934
$conn = oci_connect('scott', 'tiger', 'xxx')
or die('Cannot connect');
$stmt = oci_parse($conn, "select lobdata from lobtest");
oci_execute($stmt);
list($lob) = oci_fetch_row($stmt);
oci_free_statement($stmt); // 5.1.2 crashes without this
if($lob) {
$data = $lob->read(256);
//$data = $lob->load(); // this fails too
var_dump($data);
$lob->free(); // 5.1.2 crashes without this
