 If you set {{{fields}}} to {{{ids}}} or {{{id=>parent}}} in a
 {{{WP_Query}}} instance, {{{WP_Query::post_count}}} does not get set, so
 {{{WP_Query::have_posts()}}} returns {{{false}}}. It shouldn't.

 To test:

 {{{
 $q = new WP_Query( array( 'posts_per_page' => -1 ));
 var_dump( $q->have_posts() );

 $q = new WP_Query( array( 'posts_per_page' => -1, 'fields' => 'ids' ) );
 var_dump( $q->have_posts() );
 exit();
 }}}

 You get this for free just by setting {{{WP_Query::post_count}}} - patch
 attached
