Angular v6 build with AOT and buildOptimizer failed at runtime

After upgrading to angular v6

Fails at runtime :

From the debugger : interface_1 is defined in the Closure (OEBj) :

interface_1 : {
  __esModule : true
  __proto__ : { ... }

Bug Report

Current Behavior:

Works with build without buildOptimizer:

      "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            ...
          },
          "configurations": {
            "production": {

                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.prod.ts"
                }
              ],
              "optimization": true,

              "serviceWorker": true
            }
          }
        },

Fail at runtime with "buildOptimizer": true:

      "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            ...

                  "with": "src/environments/environment.prod.ts"
                }
              ],
              "optimization": true,
              "aot": true,
              "buildOptimizer": true,
              "outputHashing": "all",
              "sourceMap": true,
              "extractCss": true,
              "namedChunks": false,
              "extractLicenses": true,
              "vendorChunk": false,
              "serviceWorker": true
            }
          }
        },

Expected Behavior:

ui-router works with build option: buildOptimizer: true
