Description:
------------
When supplying a MAGIC file to finfo_open, valid MAGIC files that were parsed correctly in PHP 7.3 - 8.0 now result in parse errors within the finfo extension.

An example of a MAGIC file that was working previously: https://raw.githubusercontent.com/laminas/laminas-validator/2.15.x/test/File/_files/magic.7.mime

The above file has been used in unit tests since the 5.6 series without issue; we only began seeing the issues when attempting to test against PHP 8.1rc1.

Test script:
---------------
$finfo = finfo_open(FILEINFO_MIME_TYPE, 'magic.7.mime'); // file referenced in Description section
echo finfo_file($finfo, 'plain.txt'); // assuming plain.txt is a text file

Expected result:
----------------
text/plain; charset=us-ascii

Actual result:
--------------
