Comment (by westonruter):

 @johnjamesjacoby Here?

 {{{#!php
 <?php
 $id   = 0;
 $post = get_post( $id );
 }}}

 That's not mocking an empty `WP_Post` object, is it? That seems to be just
 another way of doing `$post = get_post()` since an ID of `0` will result
 in the global `$post` being used. But if that global doesn't exist, then
 `$post->comment_count` would still issue a warning.
