It seems, after recompiling using PHP Version Switcher v2, the command line (CLI) version of PHP starts triggering this error:
PHP 5.6.31 (cli) (built: Sep 18 2017 00:20:10)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend Guard Loader v3.3, Copyright (c) 1998-2015, by Zend Technologies
Segmentation fault
Caused by ZendGuardLoader.so called in /usr/local/php/php.d/zend.ini
Any ideas why?
