Dart SDK 2.0.0-dev.69.0 (also present in 2.0.0-dev.68.0)

@JS()
library js_interop;

import 'dart:async';
import 'package:js/js.dart';

typedef MyFunc = void Function(Object o);

@JS()
@anonymous
abstract class Exports {
  external set foo(Function value);
  external set bar(MyFunc value);
  external set baz(void value(Object o));
  external set qux(Future<void> value (Object o));
}

@JS()
external Exports get exports;

void main() {
  // this compiles fine
  exports.foo = allowInterop(print);

  // crash
  exports.bar = allowInterop(print);

  // crash
  exports.baz = allowInterop(print);

  // something really interesting here:
  // uncommenting this line prevents compiler crash on two previous lines
  // exports.qux = allowInterop((Object o) async => await print(o));
}

Crash looks like this:

org-dartlang-sdk:///sdk/lib/_internal/js_runtime/lib/js_helper.dart@89651+1:
Internal Error: The compiler crashed when compiling this element.
The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.

Please include the following information:

* the name and version of your operating system,

* the Dart SDK build number (2.0.0-dev.69.0), and

* the entire message you see here (including the full stack trace
  below as well as the source location above).

The compiler crashed: NoSuchMethodError: The method 'localIsUsedInTryOrSync' was called on null.
