Description:
------------
If you create a new mysqli object using incorrect login details, Apache
crashes.

Version info output from mysql_* and mysqli_* functions:

mysql
Client Encoding: latin1
Client Version: 5.0.16
Protocol Version: 10
Server Version: 5.0.16-nt

mysqli
Client Encoding: latin1
Client Version: 4.1.7
Protocol Version: 10
Server Version: 5.0.16-nt

Reproduce code:
---------------
Ensure username and/or password are incorrect:

<?php $mysqli = new mysqli('localhost', 'root', 'root'); ?>

Expected result:
----------------
Incorrect login details error

Actual result:
--------------
Apache crashes. Windows error reporting shows:

szAppName : Apache.exe     
szAppVer : 2.0.55.0     
szModName : php5ts.dll     
szModVer : 5.1.0.0     
offset : 00008be4

Looks like there is a binary incompatibility in protocol when connecting
from 4.1 client to 5.0.16.

I was able to reproduce the problem under linux too.

As a possible workaround you should compile PHP against 5.0.16 client
lib.

update on that.  i made my instance of this problem go away and
php/phpmyadmin worked fine by simply making sure that i copied
libmysql.dll from the php main directory (where the phpinstall program
put it automagically) to the extensions directory (which I had added to
windows PATH).  restarted apache, problem gone.  hope this helps.

Problem still exists after trying latest snapshot.

Make sure you don't have multiple libmysql.dll's around in your system.
