So I get the DMD crash building *anything* with the release
version of DMD from git HEAD.  I generated a debug build though
and it works fine.  So it sounds like a codegen bug to me, but I
haven't taken the time to try and figure it out.  The crash I saw
was in a ctor though.  If it's anything like the crash I saw back
when OS X was moving to clang, it will be that the "this" pointer
has a bad offset.
