Hi Noam,
Following your suggestion I tried starting with "emacs -Q" and
got the same results as you did. However if I (require 'cl)
then the bug returns. (I normally require CL automatically on
starting emacs.) So perhaps it's an incompatibility between CL
and the new way that defsetf is implemented.
