Is this reported in bugzilla?
and it doesn't seem to discard any unreferenced library symbols, so the release build of my code is ~9.5MB, while it should be ~4.
Optlink does not discard unreference symbols, it just doesn't pull them in from the library. If it did always pull in everything from the library, then the minimum D executable size will be the size of Phobos.
Since that isn't happening, something else is happening with your code. I bet that those unreferenced symbols *are* being referenced. You can determine this by using the librarian to remove those 'unreferenced' symbols from Phobos, and then link, and see if there are any unresolved symbol error messages.
