Description:
------------
When executing mysql_connect with 5.2.11 running as a module under Apache 2.2.14 on a Windows 7 platform, mysql_connect times out and the browser reports "connection reset" or similar depending on the used browser. This behaviour was first observed with phpMyAdmin 3.2.3 (file library/dbi/mysql.dbi.lib.php, line 38). When changing the invocation type from module to (f)cgi, the problem disappears. This behaviour is reproducible with 5.3.1 (vc6-x86). MySQL is version 5.1, client side 5.0.51a (as reported by phpinfo).

Reproduce code:
---------------
Cf. mysql.dbi.lib.php

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Same problem with 64bit windows 7.
Sample code:
http://sg.php.net/manual/en/mysql.examples-basic.php

This would show the problem.
As long as mysql_connect() is present, the problem would occur.

Config:
Windows 7 x64
Apache 2.2.14 x86 using php5_module
PHP 5.3.1 thread safe x86 VC6
MySQL 5.1 x86

Doesn't work:

<?php
mysql_connect('localhost');
?>

mysql_errno(): 2002
mysql_error(): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

This works:

<?php
mysql_connect('127.0.0.1');
?>

I'm thinking this has something to do with IPv6 (localhost is resolving to ::1 when I ping it).

Clients like mysql's CLI (mysql -h localhost) connect without issues.

Connect to 127.0.0.1 instead or fix your OS to provide an ipv4 address 
for "localhost" instead of just ::1 which is likely what you have right 
now.
