Description

If there is a let expression inside do-clause that uses query variables, then the compiler crashes.

public function main() {
    var input = [{name: "Saman", price1: 11, price2: 12}, 
                    {name: "Saman", price1: 13, price2: 14}, 
                    {name: "Kamal", price1: 15, price2: 16}, 
                    {name: "Kamal", price1: 17, price2: 18}, 
                    {name: "Saman", price1: 19, price2: 20}];    
    _ = from var {name, price1, price2} in input
            do {
                _ = let var p1 = price1 in p1;
            };
}
