It would be great if you could report a bug when you find a crash in dart2js.

[regis, 2012/11/19 17:32:26]

I did not, because several bugs are already filed against factory redirection
support in dart2js (incl. one crash bug), and because many
factory_redirection_test are failing. But this is done now:
issue 6799.

Thank you, Regis, I wasn't aware of any crashes until I filed 6791 earlier
today.  Would you mind pointing me to the other ones as I want to bump their
priority?
