With the commandline (php.exe) it seems to work but with the mod_php-module we get the same failure. Because the testing of our application take a long time, it would be good if you can find a solution for Version 4. ------------------------------------------------------------------------ [2005-06-11 15:18:48] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
