Previous Comments: ------------------------------------------------------------------------ [2020-04-29 16:37:41] roland at nextendweb dot com I didn't originally used xdebug and xdebug was only on a single server installed. I was able to reproduce this crash on 3 different server and on two xdebug was not installed. So I do not think it is xdebug related. If I added opcache_reset() to my index.php it was good all the time. After removed, it crashed. ------------------------------------------------------------------------ [2020-04-29 16:35:18] cmb@php.net Ah, but file_cache is not enabled in your case! Can you please try with a recent PHP version on Windows, and provide a *debug* backtrace, see <https://bugs.php.net/bugs-generating-backtrace-win32.php>. ------------------------------------------------------------------------ [2020-04-29 16:32:24] cmb@php.net When file_cache is enabled, and you switch Xdebug on and off, crashes are to be expected. That issue has already been reported as bug #75886. ------------------------------------------------------------------------ [2020-04-29 15:39:44] roland at nextendweb dot com Xdebug is disabled when this crash happens.
