I have CLM :just-lisp working in SBCL, at least to the extent that it
can play the synthesized violin example.  I haven't tried getting all
the stuff with the code walker going.

I hit something very similar in clm-snd.lisp, which I reported this as
an SBCL bug, though the code that triggers it is kind of questionable
anyway:

 sprintf(buf,~A);~%   clm_send_snd(buf); free(buf);}~%"
            (apply #'lisp-to-C-format nil fstr args)))

I can't see what (varinfo-refd nil) is supposed to return, so I tend
to cut SBCL some slack where it doesn't either.  Is your ffi.lisp
problem likely to be similar?

I believe that one is somehow religious, though I forget the exact
reasoning.

I haven't tried building the ffi version yet.  I'll come back to CLM
when I have my new usb audio adaptor working properly.
