Repro steps.

Running an app compiled to es5 works, but es2015 gives a zone error.
The app compiles I mean, but it doesn't run.

The log given by the failure.

Desired functionality.

If es2015 code compiles well to es5, and runs well, it should be abled to compile to es2015 and run well.

Mention any other details that might be useful.

I am using Chrome Canary.
This is my branch of an OSS project: https://github.com/AnSyn/ansyn/tree/chrome-44
npm run start:backwards works.
npm run start does not.

Even if I use the same configuration for both, and only change the target, I still get the error.

Note!
If I use @angular/[email protected] it works fine.
