Previous Comments: ------------------------------------------------------------------------ [2020-09-21 10:50:38] requinix@php.net Use an actual debugger to step through the code as it hits that trigger_error() call. ------------------------------------------------------------------------ [2020-09-21 08:34:14] php at shyim dot de Description: ------------ I am currently testing our Software on PHP 8. Anything seems to work, but the CLI Installer fails. I did some debugging using var_dump and searching which line produces the 255 exit code without message. It was always the trigger_error calls. When I remove from the entire project all trigger_error calls, the installation step works. Test script: --------------- Unfortunately I don't know what causes it. But when you run our Installer (MySQL Database needed) it crashes always. See install.sh to how to execute the installer. Github Repository: https://github.com/shyim/php8-bug-trigger-error Expected result: ---------------- The Installer works runs with exit code 0. And a recovery/install/data/install.lock file exists Actual result: -------------- The trigger_error triggers 255 exit code without message.
