[dmd-beta] beta 2

I found a regression:

I also found what I think is another one, but I don't have time to 
reduce it right now.  In other words, if you fix the first one in short 
order it's probably not worth immediately making another release.  I'll 
get busy with isolating the second regression tonight.
