New issue 3347 by [email protected]: Optimization causes dart2js to fail in
Try Dart
http://code.google.com/p/v8/issues/detail?id=3347
Repro:
1. Install Chrome Version 36.0.1985.18 beta
2. Open http://v8.try-dart-lang.appspot.com/
3. Wait for the example to compile
4. Reload
5. Goto step 3.
Expected behavior:
The following output is printed in "See Dart / Console":
<spinner> Compiling....
Which is replaced by:
Hello, World!
Observed behavior:
At least one time in four, an exception is thrown in the compiler:
sdk:/sdk/lib/_internal/lib/js_helper.dart: [crash] The compiler crashed
when compiling this element.
Bad state: Too many elements, Error

This exception is not supposed to happen, and it has never been observed on
Chrome 35.
Also, when running Chrome with "--js-flags=--noopt", the exception doesn't
occur.
