Previous Comments: ------------------------------------------------------------------------ [2008-10-17 14:57:30] Bjorn dot Wiberg at its dot uu dot se Description: ------------ The (5.3dev200810170630) bundled Fileinfo extension does not look for /usr/share/misc/magic{.*} as suggested by http://se.php.net/manual/en/function.finfo-open.php. Setting the environment variable MAGIC works, however. So does specifying the full path to to magic file in the call to finfo_open(). When it fails to find the magic file, PHP core dumps. Reproduce code: --------------- php -d extension_dir=/apache/php/lib/php/extensions/debug-non-zts-20071006 -r '$finfo=finfo_open(FILEINFO_MIME);' Also see "Actual result" below, which illustrates all this. Expected result: ---------------- No coredump, Actual result: -------------- root@musica-lp03:/# /nynom/apache/php/bin/php -d extension_dir=/nynom/apache/php/lib/php/extensions/debug-non-zts-20071006 -r '$finfo=finfo_open(FILEINFO_MIME);' Segmentation fault (core dumped) root@musica-lp03:/# gdb /nynom/apache/php/bin/php ./core GNU gdb 6.0 Copyright 2003 Free Software Foundation, Inc.
