Operating system: IBM AIX 5.3 (5300-08-01-0819)
PHP version: 5.3CVS-2008-10-17 (snap)
PHP Bug Type: Filesystem function related
Bug description: Fileinfo does not look for /usr/share/magic{.*} and coredumps
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:
--------------
