>             Project: Thrift
>          Issue Type: Bug
>          Components: Haskell - Compiler
>         Environment: GHC 7.6.3

> If we have a service definition that looks something like:
> {code:none}
> struct ServiceRequest {
>   1: optional bool shouldWork;
> }
> service MyService{
>   void myService(1:ServiceRequest request = {});
> }
> {code}
> The code generation relating to the service call includes an invocation like this:
> {code:none}
> ... = default_ServiceRequest{}
> {code}
> Which is invalid as empty record updates are not allowed.
