Calling .siblingsLeft on an undefined statement hangs execution.

The following code hangs execution on the Clava Web Tool.

println(
    $scope.lastStatement.siblingsLeft[0].code
);

Curiously, $scope.lastStatement is undefined. One would expect that calling a method on an undefined object would result in an exception being thrown. However that is not the case here. Execution continues indefinitely.
