In revision r26267, the dart2js compiler crashes when processing the test:

~/dart $ sdk/bin/dart2js --out=/tmp/out.js tests/co19/src/Language/15_Types/4_Interface_Types_A11_t02.dart
tests/co19/src/Language/15_Types/4_Interface_Types_A11_t02.dart:1:1: 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 (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).
