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.
