wp_resource_hints not found

WordPress 4.6-RC1 raise this exception:

Warning:  call_user_func_array() expects parameter 1 to be a valid callback, function 'wp_resource_hints' not found or invalid function name in \wp-includes\plugin.php

Looks like a corrupted/failed update to me.

I downloaded the release from ​https://wordpress.org/wordpress-4.6-RC1.zip and couldn't reproduce this. wp_resource_hints() is properly defined in wp-includes/general-template.php.

Can you re-install 4.6 RC1 again, either by downloading ZIP file and installing manually or by using wp-admin/update-core.php, to see if the error still exists?
