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")

Another piece of information. I have a more or less identical production server which isn't having this problem. But I haven't run dist-upgrade on it recently. The latest version of slime it has is v2.26.1. It's running sbcl 2.2.1.
The system giving me trouble is v2.27 slime and 2.2.2 sbcl.

Yes, I can repeat this in LispWorks after setting
(setq hcl:*handle-existing-defpackage* '(:error :modify))
I assume this is the same thing that sb-ext:*on-package-variance* is designed to control.
It happens in v2.26.1 as well.
The problem is that defslimefun exports the fun name. In swank-repl.lisp, there is a defpackage followed by some defslimefun forms for names that are not exported in the defpackage.
During compilation of swank-repl.lisp, the defpackage and exports are evaluated at compile time.
During later compilation of swank-presentations.lisp, the previously compiled swank-repl.lisp is loaded (this is hidden by a binding of *load-print*).
As a result, the defpackage is evaluated again with fewer exports than in the current state of the package, which has undefined consequences according to the ANSI CL standard (see http://www.lispworks.com/documentation/HyperSpec/Body/m_defpkg.htm).
The only portable fix is to move the exports into the defpackage.

Try (setf sb-ext:*on-package-variance* '(:warn (:swank :swank-backend) :error t)) instead.
