Your strace indicated that you indeed use the opcache file cache and the linked test script covers precisely your situation: https://github.com/php/php-src/blob/master/Zend/tests/unused_shared_static_variables.phpt ------------------------------------------------------------------------ [2017-03-20 16:50:05] georgestephanis at automattic dot com Howdy! I meant -- yes -- that the ini_set() would be in the file including test_class.php not in test_class.php directly. We've had reports of this in several environments thus far, and I've been able to duplicate it in testing in Siteground's 7.1 configuration. I'm not hugely intimately familiar with Siteground's setup -- perhaps it's contingent on the web server or fastcgi mode? ------------------------------------------------------------------------ [2017-03-07 11:08:54] spam2 at rhsoft dot net he means whatever file includes the code-snippet which is clear because otherwise ini_set() would not make any sense in context of diable opcache since it's too late - anways, no crash with 7.1.3RC1 [harry@rh:/www/beta.rhsoft.net/crash]$ cat test.php <?php require 'include.php'; [harry@rh:/www/beta.rhsoft.net/crash]$ cat include.php <?php class Test_Class { public static function init() { static $instance = NULL; $instance = new Test_Class(); return $instance; } } class Test_Class_Raw extends Test_Class {} [harry@rh:/www/beta.rhsoft.net/crash]$ php -v PHP 7.1.3RC1 (cli) (built: Feb 28 2017 12:34:57) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies [harry@rh:/www/beta.rhsoft.net/crash]$ ------------------------------------------------------------------------ [2017-03-07 10:56:26] andrew dot nester dot dev at gmail dot com I was trying to reproduce it but no success.
