Hi.
I constantly get following error while analyzing different files:

PHP Notice: Uninitialized string offset: 0 in
/home/fike/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Stan
dards/PEAR/Sniffs/Commenting/FileCommentSniff.php on line 606

I can confirm that it happens when @package tag starts with underscore,

however, i think i've encountered this in different scenarios. The
minimal
scenario that triggers error is pasted below.

Test script:
---------------
<?php
/**
  * @package _helpers
  */
class MigrationHelper
{
}

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