The fast CGI process crashes when PHP calls getenv() with a second parameter (local_only) of false. It's fine if the second parameter is true. It does not crash on the previous version 7.2.0. PHP 7.2.1 on linux also fine. We are wondering if this is a windows platform-specific problem. Could this be related to Bug #75574 which was released in 7.2.1? Test script: --------------- <?php getenv('HTTP_ACCEPT_LANGUAGE', false); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75794&edit=1
