I cannot give exact steps to reproduce.. but my app was working fine on angular 4.0.0-rc.6 and angular-cli 1.0.0-rc.4. As of today I am getting the error below. I have tried reverting to the older versions but the error persists.
I note that the error is thrown in @ngtools/webpack and that there was an update to this 14 hours ago.
The log given by the failure.
