> The following query returns {{x, 1},{x, 2}} with 2.7.1 and 2.10.1 as expected:
>  PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
>  SELECT *
>  WHERE {  }
>  VALUES ?x { 1 2 }
> The following query returns {{sum,3}} with 2.7.1. With 2.10.1, it returns no results.
>  PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
>  SELECT (SUM(?x) AS ?sum)
>  WHERE {  }
>  VALUES ?x { 1 2 }
> The following query returns {{count,2}} with 2.7.1. With 2.10.1, it returns {{count,0},{count,0}}.
>  PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
>  SELECT (COUNT(?x) AS ?count)
>  WHERE {  }
>  VALUES ?x { 1 2 }
> The queries work as expected with 2.10.1 if the VALUES is moved into the WHERE. e.g.
>  PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
>  SELECT (COUNT(?x) AS ?count)
>  WHERE { VALUES ?x { 1 2 } }
