Description:
------------
When I run the example script using my browser, there is a segmentation fault on the call to $result->fetch_array(MYSQLI_ASSOC) on line 16. When I run it from the command line, the script appears to work. The segmentation fault only occurs when fetching the associative array. Using MYSQLI_NUM works, but MYSQLI_BOTH also crashes.

Reproduce code:
---------------
<?php
include "../../secrets/rootmysqlpass.inc.php"; // only defines $rootpass
$mysqli = new mysqli("localhost", "root", $rootpass, "World");
printf("Host information: %s\n", $mysqli->host_info);
/* check connection */
if (mysqli_connect_errno()) {
   printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
$result = $mysqli->query($query);
/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
$result->close();
$mysqli->close();
?>


Expected result:
----------------
Kabul (AFG)
Qandahar (AFG)
