initialize this value to something since its passed on line 85, or change line
85 to pass a constant value

Done. I also realized we should initialize status_code in
ServiceWorkerResponse's default constructor.

+  ServiceWorkerResponse response;
   if (message.type() != ServiceWorkerHostMsg_FetchEventFinished::ID) {
     NOTREACHED() << "Got unexpected response for FetchEvent: "
                  << message.type();
-    callback.Run(SERVICE_WORKER_ERROR_FAILED, response.a);
+    callback.Run(SERVICE_WORKER_ERROR_FAILED, result, response);
     return;
   }
