OK, I can confirm now that this is a regression in Angular, see the details in https://github.com/angular/angular/issues/15420.

Depending on the team’s feedback it will be either fixed today or I will work-around it here by renaming the offending util function. In any case I’m planning to cut a 4.0.0 compatible release today or tomorrow morning the latest.

I can confirm this one. This is definitively a regression in rc.6 or "@ngtools/webpack": "1.2.14" as the same code works perfectly fine with rc.5 / “@ngtools/webpack”: “1.2.13”.

The root cause / error is:

10% building modules 3/3 modules 0 activeModuleNotFoundError: Module not found: Error: Can’t resolve ‘./…/…/$$_gendir/demo/src/app/app.module.ngfactory’ in ‘/Users/pawelkozlowski/work/gitrepos/pkozlowski-opensource/core/demo/src’

I’m going to narrow it down and check with the rest of the Angular team to track it down / fix. At the moment it looks like an issue in the Angular. Thx for reporting.
