Hello all,

I have an CL-PPCRE that was compiled with an SBCL running in a shell (Debian/common-lisp-controller). Now, I see the error below when trying to load cl-ppcre via SLIME. I suspect that this is a coding issue again (SB-IMPL::*DEFAULT-EXTERNAL-FORMAT* is :latin1, slime-net-coding-system is iso-latin-1-unix).

Did anyone of you run into that problem and know a solution? Apropos: deleting api.fasl makes SLIME loading work, but then the error occurs when loading from an SBCL instance being run from inside a shell.

Thank you, Nicolas

The class SB-PRETTY:PRETTY-STREAM was not changed, and there's no guarantee that the loaded code (which expected another layout) will work. [Condition of type SIMPLE-ERROR]

Do you use the `slime-presentation-streams' contrib? What happens when you do not use it?

-T.

You are right, it may be a problem with presentations. Looking at the startup messages, I see the following:

;; loading #P"/var/cache/common-lisp-controller/1000/sbcl/swank/fasl/sbcl-0.9.16-linux-x86/swank-presentations.fasl" ;; loading #P"/var/cache/common-lisp-controller/1000/sbcl/swank/fasl/sbcl-0.9.16-linux-x86/swank-presentation-streams.fasl" WARNING: change in instance length of class PRETTY-STREAM: current length: 25 new length: 27 STYLE-WARNING: redefining MAKE-PRETTY-STREAM in DEFUN STYLE-WARNING: redefining MAYBE-OUTPUT in DEFUN STYLE-WARNING: redefining OUTPUT-LINE in DEFUN STYLE-WARNING: redefining OUTPUT-PARTIAL-LINE in DEFUN STYLE-WARNING: redefining FORCE-PRETTY-OUTPUT in DEFUN

which indicates some problem. Could you tell me how to switch off presentations?

Thank you, Nicolas
