I did a little digging around to see where this issue might have been introduced. We ported libmagic
to 5.40 in 8.1, and I wonder if this might have introduced a regression: https://github.com/php/php-src/commit/3b9173dc8f3bda99e87003f6b6b2a16fa25c1b72

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:
--------------
