Class constructor BehaviorSubject cannot be invoked without 'new' in angular app with es6 target

[IlyaSurmay]

RxJS version:
5.5.4

Code to reproduce:

1. Clone this repo: https://github.com/ShinDarth/angular-test-app
2. npm install
3. ng serve --aot or ng serve --prod
   then you can install rxjs 5.4.3 and app will work fine.

Expected behavior:
App works as expected

Actual behavior:
App throws Class constructor BehaviorSubject cannot be invoked without 'new' at start

Additional information:
Everything works fine if I downgrade rxjs to 5.4.3. Looks like regression or a breaking change

Are there any news about this issue? It looks quite serious...

I tried using version 5.5.6 and I get:

ERROR Error: Uncaught (in promise): ReferenceError: a296996 is not defined

this happens only when the compile target is es6. The bug does not affect es5.

I'm looking into it... but honestly a minimum reproduction is what we want.

[benlesh]

Seems like it's been fixed downstream. I have no reproduction now.

I'm not entirely sure what the code was that you thought should work, so I'm not sure what to test.

@benlesh please reopen this because I've just tried using version 5.5.7 and the issue is still the same.

Also, as mentioned in the original issue report, there is a repository which reproduce the issue:

- Clone this repo: https://github.com/ShinDarth/angular-test-app
- npm install
- ng serve --aot or ng serve --prod

then you can install rxjs 5.4.3 and app will work fine.

This is what I get after cloning https://github.com/ShinDarth/angular-test-app, running npm install and then ng start --prod:

rxjs version in package-lock.json:

@benlesh please can you check this?
