Bug description:  $_POST not working properly

Description:
------------
when in at least two fields of the HTML form are entered identical data
and the register_globals is set to off, sending the data using method POST
gives the $_POST array empty.

There is no problem when the data are different.

Reproduce code:
---------------
<form action='login.php' method='post'>
<input type=text name=login size=15 maxsize=10>
<input type=password name=password size=15 maxsize=10>
<input type=submit value=Login>
</form>

Expected result:
----------------
1. first example
as login entered "test"
as password eneterd "test" 

expected
$_POST['login']=test
$_POST['password']=test

2. second example
as login entered "abcd"
as password eneterd "efgh" 

expected
$_POST['login']=abcd
$_POST['password']=efgh

Actual result:
--------------
1. first example result - incorrect
$_POST is empty.

1. second example result - data are correct
$_POST['login']=abcd
$_POST['password']=efgh
