Repro steps.

Given an example file example/foo.ts

export function foo(): number { 
  return 1;
}

Given an example/index.ts file such as

export * from 'foo.ts';

When you have an aliased import such as

import { foo as exampleFoo } from './example';

The import works fine in development with ng serve, however whilst ng build --prod --aot succeeds, the resulting code does not run due to an error TypeError: Cannot read property 'apply' of undefined

If you change the import to not use the barrel file, the resulting compiled code is fine. i.e.

import { foo as exampleFoo } from './example/foo';

The log given by the failure.

When viewing the dist code:
TypeError: Cannot read property 'apply' of undefined

No errors during ng build.
No errors when using ng serve.

Desired functionality.

Consistency between development and production builds for imports.

Mention any other details that might be useful.

Can you try with Angular 4.3? The AOT compiler received some major updates and may resolve your issue.

Also, a production build automatically includes AOT. You don't need to add the "--aot" option.

Is this getting any attention? We are experiencing this in 5.2 as well

Experiencing this as well in version 6

Problem goes away when you build with --build-optimizer=false
