undeclared identifier in c code

[jupvfranco]

I'm getting an error when I compile this small program.
Use of undeclared identifier 'res' and I don't undertand why.

class Main 

class Foo
    def getBar(): Bar {
        new Bar
    }
    def foo(): Bar { 
        let res = new Bar
        in {
            let foo = new Foo 
                v = get foo.getBar()
            in () ;
            res         
        }
    }
passive class Bar 
    x: real
    y: real 

I checked the generated C code and the variable res is declared as '_res_1' and used in the return expression as 'res'
Bar_data* _res_1 = _new_0;
... some code here ...
return res;

Thanks

Fixed as of 2b8edce. The culprit was the backend unsubscribing more variables than it was supposed to.
