I doubt it's an sbcl issue. What you have is an attempt to dump the
literal object which prints as ?GO-VAR1 (which is presumably some kind
of a structure or object; it's difficult to tell from your message)
into a compiled file, without telling the lisp system how to do that
(defining a user method on MAKE-LOAD-FORM is how you do that).
My guess is that you've hit C-c C-c on something, which in slime
compiles the form to a file and then loads the resulting file. The
easiest workaround is probably to use C-x C-e instead, which will not
attempt file compilation, but instead simply evaluate the form. On
the assumption that your objects printing as ?FOO have some kind of
similarity semantics, the proper fix would be to define a
MAKE-LOAD-FORM method applicable to them.
