Description:
------------
PHP/Apache is reporting default when trying to use finfo_file() method.

When opening from web (through apache2), segfault is reported in error log:

[Wed Oct 23 14:32:25 2013] [notice] child pid 29084 exit signal Segmentation fault (11)

When executing from cli e.g. php -q test.php, output is okay.

php -v

/usr/sbin/apache2 -v
Server version: Apache/2.2.25 (Unix)
Server built:   Sep 20 2013 14:16:11


Test script:
---------------
<?php
$finfo = finfo_open(FILEINFO_MIME_TYPE, null);
$info = finfo_file($finfo, "index.php");


Expected result:
----------------
mime type of the file should be returned

Actual result:
--------------
nothing - apache/php segfaults
