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. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75570&edit=1
