Unfortunately the bug only shows randomly during shutdown after a very complex script. The best I could do is to give you access to my machine in case the crash happens again, but I'm afraid I can't do much more right now. ------------------------------------------------------------------------ [2007-11-25 17:31:26] jani@php.net 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. ------------------------------------------------------------------------ [2007-11-24 15:20:57] matteo at beccati dot com FreeBSD, PHP 5.2.4: ./configure --with-apxs2=/usr/local/sbin/apxs --with-mysql=/usr/local --with-pgsql=/usr/local/pgsql --with-zlib --with-iconv=/usr/local --enable-bcmath --enable-ftp --enable-mbstring --with-mcrypt=/usr/local --with-mhash=/usr/local --with-curl=/usr/local --with-xml --with-xmlrpc --with-gettext --with-gd --enable-gd-native-ttf --with-png --with-png-dir=/usr/local --with-jpeg --with-jpeg-dir=/usr/local --with-freetype-dir=/usr/local --with-ttf=/usr/local --enable-pcntl --enable-sockets --enable-sigchild --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm No extensions loaded in php.ini.
