Bug description:Segfault on fetch_object on used result Closed DB Pointer
Description:
------------
When using MYSQLI_USE_RESULT, then immediately closing the database, and
then attempting to fetch_object() the result will result in a segmentation
fault.
PHP does not segfault if using fetch_array() or fetch_assoc().
Test script:
---------------
<?php
$db = new mysqli("127.0.0.1", "root", "root", "test");
$result = $db->query('SELECT 1', MYSQLI_USE_RESULT);
$db->close();
$result->fetch_object();
Expected result:
----------------
An exception or php fatal error that states the database was closed.
Actual result:
--------------
[root@devz user]# /usr/bin/php segfault.php
Warning: mysqli_result::fetch_object(): Error while reading a row in
segfault.php on line 15
Segmentation fault
