When I am in the SLDB, the manual states that I can display the associated source code by hitting the <v> key. However, when I do this I just get a message in the minibuffer:
Cannot find source for frame: #<address #??????> NIL #<address #??????>
The center value is sometimes T.
I am running CLISP 2.35 as my base LISP. Is this the problem or is the function broken for all Lisp implementations?
