If you could tell us what execute() is trying to execute, it would be useful. Did you read my email?

Once you get function name and file name caused the segfault, it should be easy to write short script reproduce the segfault. -- Yasuo Ohgaki -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
