----------------------------+-----------------------------
 I've been creating a new plugin based that adds some pages to the admin
 menu using the admin_bar_menu action. When using this action with a new
 WP_Query the global $post is being reset.

 I've been able to work around this for now by temp setting and resetting
 the $post variable.

 This certainly seems like a bug, as I see no reason to not make a new
 WP_Query in the admin bar.

                 global $post;
                 $temp_p = $post;

                 $args = array(
                         'post_type' => 'page',
                         'post_status' => array(
                                 'publish', 'pending', 'draft', 'auto-
 draft', 'future', 'private', 'inherit'
                         ),
                         'posts_per_page' => -1,
                 );
                 $listpages = new WP_Query( $args );

                 if ( $listpages->have_posts() ) :

                         $args = array(

                         $wp_admin_bar->add_node( $args );

                         while ( $listpages->have_posts() ) :
 $listpages->the_post();

                         endwhile;
                 endif;

                 wp_reset_postdata();
                 $post = $temp_p;
