ID: 45973 Updated by: jani@php.net -Summary: segfault when setting include_path to concat. of non-defined ${include_path} Reported By: olivier dot berger at it-sudparis dot eu -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: Debian lenny PHP Version: 5.2.6 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2008-09-02 13:00:01] olivier dot berger at it-sudparis dot eu Description: ------------ If include_path wasn't set already, setting it to some concatenation of ${include_path} causes a segfault. Seems different from #37002, AFAICT More details in Debian bug : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497453 Reproduce code: --------------- For instance, if /etc/php5/apache2/php.ini doesn't contain any include_path definition, like is by default in Debian : ; UNIX: "/path1:/path2" ;include_path = ".:/usr/share/php" then setting the following in for instance /etc/php5/conf.d/zend.ini : [Zend] include_path = ${include_path} ":/usr/share/php/libzend-framework-php" leads to segmentation fault. Expected result: ---------------- I guess referencing variables no yet explicitely set, but having default values should return their default value. Uncommenting the default include_path in /etc/php5/apache2/php.ini allows it to work. Actual result: -------------- Apache segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45973&edit=1
