 Hello
 I'm in a case where get_object_term_cache() in get_the_terms() returns an
 empty array evenif I have term (as post_format) for the posts.

 in
 {{{
         $terms = get_object_term_cache( $post->ID, $taxonomy );
         if ( false === $terms ) {
                 $terms = wp_get_object_terms( $post->ID, $taxonomy );
                 if ( ! is_wp_error( $terms ) ) {
                         $term_ids = wp_list_pluck( $terms, 'term_id' );
                         wp_cache_add( $post->ID, $term_ids, $taxonomy .
 '_relationships' );
                 }
         }
 }}}

 checking if  $terms is also empty solves the problem.
 if you think it's a "bug" I'll create the patch.
