Hi, I recently upgraded my development web server from PHP 4.0.6 to PHP 4.1.2 in the wake of the security alert.
Details: SCO Openserver 5.0.6 Apache 1.3.20 with SSL PHP 4.1.2 Libxml 2.4.16 Mysql 3.23.48 PHP configure: ./configure \ --with-apache=/u/apps/apache_1.3.20_wssl \ --with-mysql=/usr/local/mysql-3.23.48 \ --with-dom \ --enable-track-vars \ --enable-trans-sid \ --with-zlib-dir=/usr/local/lib Apache Configure ./configure \ --prefix=/usr/local/apache --activate-module=src/php4/libphp4.a --enable-module=rewrite Since the upgrade, I am receiving Segementation Faults in the log files when accessing some of my existing code. It is not happening all the time, only occasionally. I haven't been able to pin point where the problem is. Here is the output from the backtrace - I ran the php binary on one of the files that segfaulted and it created a core dump. Here is the output from the gdb of the core: ---------------------------------------------------------------------------- ----------- # gdb /usr/local/bin/php core Copyright 2000 Free Software Foundation, Inc.

One of the files I'm getting the fault with is using the "require" command. If I comment out the "require" command, this file seems to work. Thing is - alot of other files are using the require command on this same file, and they do not have a segmentation fault. I checked out the file that is being required - nothing looks wrong with that. Ran: /usr/local/bin/php <file> on the required file - all is ok. No core dump. I cannot put this release of PHP onto the production server because of these problems, but I need to get the release out because of the security alert. :| What other details can I check?
