Comment (by jrf):

 Replying to [comment:16 andraganescu]:
 > While testing on PHP 8 I found that any page (home or archive) will
 return 404 as if there were no posts available. The problem appears to be
 in `wp-includes/class-wp-query.php` at line `762`, where the new
 [https://wiki.php.net/rfc/string_to_number_comparison Saner string to
 number comparisons] makes it so that `"" < 0 === true`, so `$qv['p'] < 0`
 is `true` since the default for `$qv['p']` is `string(0)`.


 This was already fixed in [48960]
