Comment:

 The warning comes from `WP_Query::rewind_posts()`, called as part of
 `::have_posts()`.

 If I'm reading the code correctly, it can be triggered if
 `$this->post_count` is greater than zero but `$this->posts` is empty,
 though it's not quite clear to me how to reproduce this scenario. The
 queries from comment:4 or comment:7 don't seem to trigger it in my
 testing.
