Description:
------------
Since upgrading to Php 7.1.12 from 7.1.10, I'm seeing sporadic errors in an instance of PHP-based web application called Phabricator <https://github.com/phacility/phabricator>.

> Error while loading file "/srv/phabricator/phabricator/src/infrastructure/diff/view/PHUIDiffGraphView.php": Narrowing occurred during type inference. Please file a bug report on bugs.php.net

The file in question is here:
<https://github.com/phacility/phabricator/blob/9bd6a3705559b16c75595a06d9d726274bd5be6d/src/infrastructure/diff/view/PHUIDiffGraphView.php>.

I have no knowledge of the PHP internals but grepping the PHP codebase appeared to indicate that the error message is generated by the opcache component.

I note that the changelog for PHP 7.1.9 listed a fix for this error.

aladdin at polikoff dot ru: which PHP version?

this bugreport is for 7.1.12 and current is 7.1.14 while in the meantime since this bugreport was opened more than one fix for the topic "Narrowing occurred during type inference" was implemented

so for the sake of god be precise with your informations about the uzsed runtime versions, you even don't tell the Wordpress version nor if you also use CentOS 7.4 and from where your packages are
