while I was compiling cl-pdf, sbcl detected some invalid uses of delete in iterate.lisp. I checked that these errors were there in the iterate 1.4 release available from asdf-install.
Indeed, (delete ...) has side-effects and doesn't preserve its second argument. Thus, a minimally disruptive patch would be to replace (delete entry index) with (setf index (delete entry index)) twice, and (delete nil temps) with (remove nil temps). Someone who understands the code better audit what is being done by the considered functions. Patch attached.
Happily these errors didn't seem to affect the behaviour of cl-pdf.
I've fixed the iterate version in cl-pdf. (It will show up in the next commit)
