I tried to build DMD git for dpaste, so people can play with UDA 
but DMD segfaults when building Phobos

Well, anyways, I fetched package prepared in first post.
So folks, you can play with UDA on http://dpaste.dzfl.pl - by 
picking DMD2 git - without messing with DMD packages in your OS :)

Also if I declare string with UDA inside main() I get error:
