 When the version of PHP was 7.2.0, count() will now yield a warning on
 invalid countable types passed to the array_or_countable parameter.

 /wp-includes/post-template.php

 Line:284

 {{{
 if ( $page > count( $pages ) )
      $page = count( $pages );
 }}}

 to

 {{{
 if ( $page > count( $pages ? : [] ) )
      $page = count( $pages ? : [] );
 }}}
