Comment (by bobz):

 This was the fix in my case, I'm using relative permalinks without
 trailing slash.

 {{{#!php
 <?php
 add_filter( 'redirect_canonical', function( $redirect_url, $requested_url
 ) {

     $redirect  = parse_url( $redirect_url );
     $requested = parse_url( $requested_url );

     // Prevent redirect to exact same page
     if ( strtolower($redirect['path']) == strtolower($requested['path']) )
     {
         return false;
     }

 }, 101, 2 );
 }}}
