I asked this question over on sbcl-help already. Stas objected. So I'll ask it again here.
Last night I started running into the debugger when trying to start slime in emacs. This morning I
decided to delete all my .slime/ fasls, all of .cache/common-lisp/ all of ~/quicklisp and start
with a fresh copy of quicklisp.lisp. I updated my arch system (slightly newer version of emacs)
then tried to reinstall quicklisp.
The problem occurs upstream of emacs ever being started. I can reproduce the problem with these
steps:
$ rm -rf .slime .cache/common-lisp/* quicklisp
$ curl -O https://beta.quicklisp.org/quicklisp.lisp
$ sbcl --load quicklisp.lisp
* (quicklisp-quickstart:install)
* (ql:quickload "quicklisp-slime-helper")
To load "quicklisp-slime-helper":
Load 1 ASDF system:
asdf
Install 3 Quicklisp releases:
alexandria quicklisp-slime-helper slime

Neither locate nor find show any signs of any other copy of swank or slime on this system. The only
thing in my .sbclrc is this:
;;; The following lines added by ql:add-to-init-file:
;;#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp" (user-homedir-pathname))))
(when (probe-file quicklisp-init)
(load quicklisp-init)))
;;; Added this to test reading bad char streams
(setf sb-impl::*default-external-format* :utf-8)
;;; Added this so I can change the names of package symbols and get

I'm running out of ideas. Does anyone have any?
Thanks.
