Thank you for this bug report. To properly diagnose the problem, we

still happens - "Apache HTTP Server has encountered a problem and needs
to close.  We are sorry for the inconvenience."

phpinfo says->

don't think I can get any newer than that :)

Description:
------------
Using mysqli_stmt_fetch or $stmt->fetch crashes apache/php

Broken with both mysql 5.0 and 4.1 

Reproduce code:
---------------
$mysqli = mysqli_connect("localhost", "root", "password",
"db");

$mysqli->query("CREATE TABLE IF NOT EXISTS temp (id INT NOT NULL)");

$mysqli->query("INSERT INTO temp (id) VALUES
(1),(2),(3),(4)");


$stmt = $mysqli->prepare("SELECT id FROM temp");

$stmt->execute();

$stmt->bind_result($id);

$stmt->fetch();
var_dump($id);

$stmt->close();


$mysqli->query("DROP TABLE temp");
$mysqli->close();

Expected result:
----------------
1

Actual result:
--------------
Apache/php go boom - I'd send a backtrace but until I get nice "I'm on
windows and don't do C" directions that's not going to happen

I have the annoying windows dump files if they're even useful

trying the same thing procedural style does the same thing - through
commenting out trial and error the actual crash occurs on the
$stmt->fetch() line
