Like the "Generating backtrace, without compiler, on Windows" section. ------------------------------------------------------------------------ [2018-01-04 21:48:44] tchepelsky at gmail dot com See previous comment. ------------------------------------------------------------------------ [2018-01-04 21:47:08] tchepelsky at gmail dot com The bug generating backtrace for "Win32" does not provide adequate instructions to my specific situation. I will need further help for this case. https://bugs.php.net/bugs-generating-backtrace-win32.php From the link above, this is what I have done so far: 1) Downloaded and installed Microsoft Visual Studio Community 2017. 2) Downloaded and extracted the "debug-pack" into my "php" folder which contains PHP 7.1.13 VC14 Thread Safe (x64). 3) Started my website and tried to log into my phpBB forum account, which resulted in the same "CGI / FastCGI has stopped working" message again. There was no additional or alternative option to click "Cancel" in order to debug the process, as the instructions state as being the expected outcome. As a result, I cannot provide a backtrace until these steps have been clarified. ------------------------------------------------------------------------ [2018-01-04 20:36:28] requinix@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2018-01-04 18:00:32] tchepelsky at gmail dot com Description: ------------ Summary: "CGI / FastCGI has stopped working" (site crash) is triggered with PHP 7.1.13 VC14 Thread Safe (x64), specifically when trying to log into a registered phpBB account.
