Thanks for the fix, I have another error, not a segfault this time:
https://github.com/nicolas-grekas/symfony/releases/download/php-bugs/preload-failures-78175.tar.bz2
I run
php -S localhost:8000 -t public/
-dopcache.preload=var/cache/prod/srcApp_KernelProdContainer.preload.php
Then in another console:
php info.php
This fails with an error:
Uncaught Psr\Log\InvalidArgumentException: The log level "critical" does not exist.
Yet it exists. To debug, I added a var_dump in
vendor/symfony/http-kernel/Log/Logger.php
And it displays:
UNKNOWN:0

A partial fix is available at
https://github.com/php/php-src/compare/PHP-7.4...dstogov:bug78175?expand=1
It needs to be extended to support static variables of methods.

While funny, that's not that interesting to keep: if one wants this, it's always possible
to generate a file with the array and load it. Preloading the default static value is what would be
the most expected, to me at least :)
