Trouble shoot "Runtime compiler is not loaded"

Question

I am getting the following runtime error after building my Angular2 app with the --prod flag:

Runtime compiler is not loaded

I understand that the production builds use AoT and that runtime compiling isn't supported in this scenario.
My problem is: I am not aware of anything I am doing that would need the runtime compiler. It might even be an external component I am using.

How do I find out what component is causing this error?

Quite a few. I found out that the problem was the usage of DynamicComponent by angular2-busy. However, I found this out only because that component stopped working. Isn't there a more deterministic approach? — Daniel Hilgarth, Mar 07 '17 at 11:10
Not sure what you mean with "deterministic approach". If you create components at runtime you currently can't use AoT. See also http://stackoverflow.com/a/42619501/217408 — Günter Zöchbauer, Mar 07 '17 at 11:13
With deterministic approach I mean: How do I find out in a deterministic way WHICH component is creating components at runtime? — Daniel Hilgarth, Mar 07 '17 at 11:15
Sorry, no idea. I'd suggest you create a bug report for a better error message. — Günter Zöchbauer, Mar 07 '17 at 11:15
I also experienced this same issue and it was also caused by angular2-busy. Thanks for the tip. — MapLion, Jun 16 '17 at 08:32

I have had the similar issue with AoT compilation when I was trying to use lazy module loading using module type instead of the path.

Correct loading:

{ path: 'lazy', loadChildren: 'lazy/lazy.module#LazyModule' }

Way, I've done it (crashes AoT):

export function loadLazyModule() {
  return LazyModule;
}
export const appRoutes: Routes = [
  { path: 'lazy', loadChildren: loadLazyModule, },
];

Indeed the error message is not helpful at all, however, the stack trace is:

at Compiler.compileModuleAsync (core.js:3664)
at MergeMapSubscriber.eval [as project] (router.js:4467)

I've just made a breakpoint at compileModuleAsync function and at the stop I saw the module which was causing the error.
