 Login to wordpress fails with Warning: Illegal string offset 'user_login'
 under php 7.1.0 alpha 1.

 wp-login.php sends an empty string to wp_signon that expects an array.


 The following patch to wp-login.php seems to solves the issue:
 {{{#!php

 @@ -790,7 +790,7 @@ function retrieve_password() {

         $reauth = empty($_REQUEST['reauth']) ? false : true;

  -      $user = wp_signon( '', $secure_cookie );
  +      $user = wp_signon( array(), $secure_cookie );

         if ( empty( $_COOKIE[ LOGGED_IN_COOKIE ] ) ) {
                 if ( headers_sent() ) {
 }}}
