With antialiasing on, the error doesn't occur. (Can be reproduced with Emacs -Q, which seems to use special settings for antialiasing, or with (setq ns-antialias-text nil)). Reintroducing line spacing (which was removed for a reason) not only fixes this bug, but has global consequences. So I don't think this is the right way to fix this bug. I think we have to look at the code that draws the non-antialiased text. For now, the workaround for this is (set-frame-parameter nil 'line-spacing 2) (or setting defaut-frame-alist accordingly).
