SWANK::MAYBE-METHOD-LOCATION calls SWANK::FUNCTION-SOURCE-LOCATION
which calls CCL::EDIT-DEFINITION-P, which tries (in the DOCUMENTATION
case) to call CLASS-NAME on an EQL specializer, and that signals
an error.

When I set *inferior-lisp-program* to a copy of 0.14.3 and run it
under an unmodified SLIME, I get exactly the same behavior.

If I comment out the call to SWANK::MAYBE-METHOD-LOCATION, doing
M-. on DOCUMENTATION, I get a buffer full of method forms (the
CAR of each is the symbol CCL::STANDARD-KERNEL-METHOD).  If I
click on one of them, Emacs finds ... the wrong method in the
right source file.  (It seems to jump to the first (DEFMETHOD
DOCUMENTATION ...) form in the source file.)

I don't use SLIME, so I don't know if this ever worked.   It 
does appear that CCL::EDIT-DEFINITION-P has had a long-standing
bug that's worth fixing, though it's not clear to me that
CCL::EDIT-DEFINITION-P does anything particularly useful (that
can't be done in other ways.)
