ID: 40641 User updated by: jfgingras at cegep-ste-foy dot qc dot ca Reported By: jfgingras at cegep-ste-foy dot qc dot ca -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: FreeBSD 6.1-RELEASE PHP Version: 5.2.1 New Comment:
Well, if that can help.. PHP with --enable-debug and no extension doesn't crash if open_basedir is defined. I'll have to test this with --disable-debug. I'm buidling the extensions we use for the debug version and see if I can reproduce the crash. Previous Comments: ------------------------------------------------------------------------ [2007-02-26 18:32:06] jfgingras at cegep-ste-foy dot qc dot ca I'll keep trying generate a backtrace for httpd, but gdb doesn't like that very much. Since I can't stop our production server, I have create an exact duplicate of httpd.conf and name it httpd-debug.conf and simply change the Listen directive and my VirtualHost. I launch httpd directly from command line like this: /usr/local/sbin/httpd -X -f /usr/local/etc/apache2/httpd-debug.conf And the server start ok, and crash as expected when I enter a directory with open_basedir defined. But I can't manage to start it via gdb, here's what happen: [EMAIL PROTECTED] apache2]# gdb /usr/local/sbin/httpd GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2007-02-26 15:49:36] jfgingras at cegep-ste-foy dot qc dot ca Description: ------------ If open_basedir if defined in a <Directory>, any call to a php file, event if this file is empty, will either throw a Bus error or a Segmentation fault. This problem appears as soon as I upgraded php 5.1.6 to 5.2.1 I didn't change anything in any configuration file of apache, and I did not upgrade apache either. My Apache version is 2.0.58 When I remove the open_basedir directive, it solve the problem. Here's the logfile of apache: [...] [Mon Feb 26 09:21:43 2007] [notice] child pid 31432 exit signal Segmentation fault (11) [Mon Feb 26 09:27:13 2007] [notice] child pid 65784 exit signal Bus error (10) [Mon Feb 26 09:27:44 2007] [notice] child pid 65537 exit signal Segmentation fault (11) [Mon Feb 26 09:28:27 2007] [notice] child pid 68909 exit signal Bus error (10) [Mon Feb 26 09:34:19 2007] [notice] child pid 32270 exit signal Bus error (10) [Mon Feb 26 09:36:58 2007] [notice] child pid 68902 exit signal Bus error (10) [Mon Feb 26 09:37:13 2007] [notice] child pid 69863 exit signal Bus error (10) Reproduce code: --------------- Here's what I have in my <Directory>: <Directory /var/www/htdocs/stages/> php_admin_value open_basedir /var/www/htdocs/stages php_admin_value upload_tmp_dir /var/www/htdocs/stages/tmp php_value register_globals 1 </Directory> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40641&edit=1
