Similar issues can be seen in the sites as well (which also work without opcache just fine). All the issues seem to be related to Pimple, or offsetGet($id) call which seems to have more or less random value $id passed to it. Sometimes $id = '', sometimes the value of the $id comes from a previous offsetGet() call and once it even had value from the following method call $this->initializeController().. Meaning that the $id = 'initializeController', not $id = 'task' as written in the code. For some reason in the last case making a random change (adding a whitespace) in the affected file fixes the issue until opcache gets cleared. I'm not sure if the issues are related, is $units an ArrayAccess object? ------------------------------------------------------------------------ [2018-09-26 14:44:48] alex dot a dot pott at gmail dot com If I change code in EntityQueryTest:141 from list($field_name, $langcode, $values) = $units[$key]; $entity->getTranslation($langcode)->{$field_name}[] = $values; to list($field_name, $langcode, $values) = $units[$key]; $entity->getTranslation($units[$key][1])->{$units[$key][0]}[] = $units[$key][2]; It works fine. I've tried to produce a snippet that just does the list() and cause the error but I've not been successful yet. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
