@petebacondarwin That link 404s for me, looks like the correct link for that PR is https://circleci.com/gh/angular/angular/562563#artifacts?

Tried it with the artifacts from that link and seeing the same style of error, but a different file:

Using rc.6 throws the same exception while rc.5 is the exception that @mikolaj-leszczynski posted in his original report.

Thx for verifying, @marcus-sa 👍

I am going to close this issue (since it seems to have the same root cause as #34411). Please, track #34411 and if the problem persists once the fix for #34411 has been released open a new issue with the problem details.

IMO async flag should be off by default since it doesn’t work properly and is definitely experimental.

IMO, the fact that there is bug in it does not mean that the async mode should be turned off, nor that it is experimental 😁 There is a specific bug in ngcc (as described in https://github.com/angular/angular/issues/34411#issuecomment-565765622 - i.e. that ngcc does not detect typings-only dependencies), which happens to affect the parallel (async) mode with a higher probability, but could theoretically affect serial (sync) mode (if I understand correctly). (It is just that it is much more likely to run into the issue in parallel mode.)

Anyway, let’s fix the bug and see what else comes up.
