Description:
------------
Below, you will find the code for 2 pages.

One registers a session and the other one should read it.

You can test it with or without session_start(); function but you will get the same result.

Any call to session_start() produces a new session loosing the old one.
This bug is an old one that was once solved on version 4.3.4 I believe, but please don?t take me by words.

You are fighting with this function more that one and half years with no results.
I hope that you forgive me for the above comments.
 By my opinion the function session_start(); should not create a new session automatically and the user should create one by using a new function presumably called create_session(); 
That would solve lots of problems with sessions.

Best Regards 
Sam


Reproduce code:
---------------
PAGE 1--- save as INDEX.PHP
<html>
<head><title>php 5.0.1 bug</title></head>
<body bgcolor="#FFFFFF">
<?
session_start();
$_SESSION['var']=1;
session_write_close();
"echo The session variable ist set to ". $_SESSION['var'] ."</br>";
?>
<p><a href="sub.php" target="_blank"">Test the session function by calling the sub.php file, which reads  the session variable &quot;var&quot; with the value of 1:</a>
<?// PHP 5.0.1 doesn't find sessions!?>

</body>
</html>
--------------------------------
PAGE 2 save as SUB.PHP
<?
if (isset($_SESSION['var'])&&$_SESSION['var']==1)
{
$text="You have opened the sub.php file, receiving a session variable 'var', which shuld carry the value of 1 and it works! _SESSION['var']=". $_SESSION['var'];
}else
{
$text="You have opened the sub.php file, receiving a session variable 'var', which shuld carry the value of 1 but _SESSION['var']=". $_SESSION['var'];

}
echo $text;
?>


Expected result:
----------------
Just call the index.php and find out

You can test these pages directly on my server too:

SUB.PHP has no session_start() call in it.  Without a session_start() call $_SESSION cannot possibly be populated so your code is bogus.

bogus != feedback
