Description
Since 4.1.0, it is possible to allow kernel override in config.php by setting EZP_AUTOLOAD_ALLOW_KERNEL_OVERRIDE constant to true.
The problem is that setting this constant will cause a Fatal Error if override autoload file has not yet been generated, as it does a require_once() statement of var/autoload/ezp_override.php without testing if it exists (in autoload.php)
