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. This did not happen with PHP 7.1.12 VC14 Thread Safe (x64).

Setup:

1) Windows 10 Enterprise LTSB (x64)
2) Microsoft Visual C++ 2013 (and 2015) Redistributable (x64)
3) Nginx 1.12.2
4) CloudFlare with SSL/TLS (Full)
5) PHP 7.1.13 VC14 Thread Safe (x64)
6) MySQL Community Server 5.7.20 (x64)
7) phpMyAdmin 4.7.7
8) phpBB 3.2.1
9) WordPress 4.9.1 en-CA

No errors are produced in the error.log file when the crash occurs.

I use a "start.bat" and "stop.bat" batch file to start and stop my website. For testing purposes, I am providing the code below.


start.bat:

@ECHO OFF
start C:\nginx\nginx.exe
start C:\php\php-cgi.exe -b 127.0.0.1:9000 -c C:\php\php.ini
ping 127.0.0.1 -n 1>NUL
echo starting nginx
echo .
echo ..
echo ...
ping 127.0.0.1 >NUL
EXIT
pause > null


stop.bat:

@ECHO OFF
taskkill /f /IM nginx.exe
taskkill /f /IM php-cgi.exe
Exit

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.

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.

Read the rest of the instructions. Like the "Generating backtrace, without compiler, on Windows" section.
