Repro steps
- Run
ng serve or ng build; app runs and builds fine.
- Run
ng build --prod and get error.
- Run
ng build --prod --sourcemaps and build fails silently.
Observed behavior
I'm running into the bug that I've seen mentioned elsewhere (#7509), where building in production mode fails at the Uglify step with this error:
ERROR in main.e2a4502596f798d8da48.bundle.js from UglifyJs
Unexpected token: punc ()) [main.e2a4502596f798d8da48.bundle.js:19927,4]
That it's happening in the main bundle makes me think it's my code, so I was trying to enable sourcemaps to track it down, as recommended here. However, when I enable sourcemaps, the build just quietly fails with no error message, but also no dist directory. 😭 Even with the --verbose flag, I don't see anything particularly useful -- it just gets up to 92% chunk asset optimization and then dies. (The process even exits with a 0 code!)

Desired behavior
I'd like to be able to generate sourcemaps to see where the problem is being introduced, or at least see an error message as they fail.
