Greencat crashes the dart compiler

[sturmf]

Hi, it seems I can no longer use greencat, the compiler crashes when I use it. Right now I am not sure if it is the compiler at fault or if it trips on some problematic code.

My dart SDK version is Dart VM version: 1.21.1.

[Error from Dart2JS on frontend|test/event_list_test.dart.browser_test.dart]: packages/greencat/src/store.dart:35:3: The compiler crashed when compiling this element. Store.createStore(Reducer<S, A> reducer, {S initialState, Function enhancer}) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 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 (build number could not be determined), and

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

Thanks for your report, did you report this also to the https://github.com/dart-lang/sdk team?

[alexeieleusis]

I don't know how to reproduce this bug, can you please provide more info? I guess there will be a problem with one of greencat dependencies not being strong mode.

[alexeieleusis]

Can you try upgrading greencat to 0.0.2? Which upgrades dependency on tuple to a strong mode compliant version

Hi, sorry for the delay. I now ported everything to the latest package versions. Unfortunately that meant to get rid of the dson package which took me a while. Now everything is up to date again, but I still get the crash. It also still tells me it is using the unsupported compiler. But I have no idea why. I did not select it n purpose. The code is here: https://github.com/sturmf/regatta-angular2/tree/REG-51-switch-to-redux-arc Maybe my pubspec.yam is wrong?

To get the crash you need to change into the frontend directory and in one console do a make run and in the other a make tests. I am rrunning this on Ubuntu 16.04. Sorry that I don't have a smaller sample.

[alexeieleusis]

This looks like a problem with the compiler itself.
