Comment (by SGr33n):

 First test, working:

 {{{#!php
 <?php
         wp_list_comments(
                 array(
                         'page'                  => 1,
                         'per_page'              => 10,
                         'style'                 => 'div',
                 )
         );
 }}}

 Second test (non working):

 {{{#!php
 <?php
         wp_list_comments(
                 array(
                         'page'                  => 1,
                         'per_page'              => absint( get_option(
 'comments_per_page' ) ),
                         'style'                 => 'div',
                 )
         );
 }}}

 Is returning
