Does this still happen to you with any of the actively supported
PHP versions[1]?

This doesn't seem to be fpm related as it is happening after compiling file and using opcache.
Not sure 100% if it's opcache but it's more likely than fpm. I think you might need to
provide a bit more info (like your opcache configuration and the script that causes that) so it can
be recreated by some opcache / engine dev.
