Something is wrong with closures

[Simn]

The unit tests throw this at me:

Error: Expr function(c2:Int) {
        return a26 + b17 + c2;
}
Stack error
        ops      :

This probably means that there's some disconnect between types somewhere. Relying on v_type is bad because the run-time type could be something else if captured.
