Bug #75794 [NEW]: getenv() crashes on Windows 7.2.1 when second parameter is false

From: jon at senyahnoj dot org dot uk Operating system: Windows PHP version: 7.2.1 Package: Reproducible crash Bug Type: Bug Bug description:getenv() crashes on Windows 7.2.1 when second parameter is false Description: ------------ Using PHP 7.2.1 (64 bit NTS) on (Windows Server 2012/Windows 7) + IIS FastCGI. 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?
