$host_unchecked is when dart2js is running on the VM's production mode.

$host_checked is when dart2js is running on the VM's developer mode.

So what is happening here is that there is a dynamic type error in the
implementation of dart2js. We report that as a crash. This is not a VM crash.

I think that makes perfekt sense (since this is a crash of the compiler), but
you might want to make this explicit in a comment here (I have not seen  Crash
marks on dart2js a lot, but it might very well confuse people)
