If so, could you please make the files available again? ------------------------------------------------------------------------ [2020-01-11 20:59:26] mbiebl at messageconcept dot com cgi-fcgi ======== Directive Local Value Master Value cgi.check_shebang_line 1 1 cgi.discard_path 0 0 cgi.fix_pathinfo 1 1 cgi.force_redirect 0 0 cgi.nph 0 0 cgi.redirect_status_env no value no value cgi.rfc2616_headers 0 0 fastcgi.impersonate 1 1 fastcgi.logging 1 1 ------------------------------------------------------------------------ [2020-01-11 20:53:23] mbiebl at messageconcept dot com Thanks for the switft reply. Afaics, php-cgi.exe does not actually crash. Otherwise I would expect a trace of that in the windows event log. But nothing is logged there. Neither is there anything in the PHP error log. Is it possible to actually get a backtrace if a process doesn't crash but simply exits? If so, how do I do it then? What I do have is a function trace from xdebug. See https://mynebula.net/index.php/s/F6QAZwYdLK5MaNx Btw, is there a way to attach files to this bug report? ------------------------------------------------------------------------ [2020-01-11 19:50:29] 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. ------------------------------------------------------------------------ [2020-01-11 18:43:20] mbiebl at messageconcept dot com I tried to reproduce the issue under Debian, using Apache and PHP via FPM, but was unsuccessful. So it seems specific PHP/IIS ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
