CFE crash on Dart 2.2.0 #36769

Open ds84182 opened 5 years ago

ds84182 commented 5 years ago

Code here

Haven't tried 2.3.0 builds yet, so this might have been fixed already?

Crashes with this message (in DartPad):

Error compiling to JavaScript:
main.dart:
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 (2.2.0), and

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

The compiler crashed: Crash when compiling file:///tmp/dartpadGXCKCQ/main.dart,
