when executing "ini_set('session.save_handler', 'user') 
which is in my case done by postnuke-0.7.2.1 (default-
installation) apache's errorlog says:

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

I believe this bug may have been solved in the CVS.
 [2002-11-06 13:22 UTC] fatih dot gey at 2way dot de 
Just installed cvs version 200211030600

.. doesn't work either.
 [2002-11-07 17:33 UTC] sniper@php.net 
Please add a short but complete example script which we can use to reproduce this.

<?php

s/reconstruct/reproduce/  :)
 [2002-11-12 13:38 UTC] iliaa@php.net 
Cannot reproduce this problem using the latest CVS. Do you have any other session related ini setting in your php.ini or virtual host (httpd.conf)?
 [2002-11-20 08:24 UTC] phpbug at lottasophie dot de 
Here is a sample script:
<?PHP
session_register ("test");
ini_set('session.save_handler', 'user');
?>

crashes apache.exe, while 

<?PHP
session_register ("test");
session_write_close();
ini_set('session.save_handler', 'user');
?>

does not.

Verifyed, attempting to fix it :-)

 [2002-11-20 11:50 UTC] derick@php.net 
This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

still having problems to run postnuke v0.721:
this time (snapshot 200211241830) this error occurs:

Fatal error: Cannot redeclare unixdate() in
 /[..]web/pnadodb/adodb.inc.php on line 1477

--adodb.inc.php: from line 1471 till line 1486

/*
* Also in ADORecordSet.
* @param $v is a date string in YYYY-MM-DD format
*
* @return date in unix timestamp format, or 0 if before
* TIMESTAMP_FIRST_YEAR, or false if invalid date format
*/
function UnixDate($v)
{
 if (!preg_match( "|^([0-9]{4})[-/\.]?([0-9]{1,2})[-/\.]?([0-9]{1,2})|",
($v), $rr)) return false;

if ($rr[1] <= TIMESTAMP_FIRST_YEAR) return 0;
// h-m-s-MM-DD-YY
return mktime(0,0,0,$rr[2],$rr[3],$rr[1]);
}
---EOF

config / compile reson, or was this cvs-snapshot broken?

thx
