Sorry, read "4th parameter" as if 0-indexed -- i.e. as errcontext (5th param)

Description:
------------
Probable ingredients:
* preloading
* big set of files to cache
* strict_types
* error_handler receiving NULL as 4th parameter
* monolog
Test script:
---------------
git clone https://github.com/m6w6/php-crash-preload-error_handler
cd php-crash-preload-error_handler
composer install
./run.sh
