Hello,

As discussed with Pierre at the R-B Summit, ‘sbcl-next’ lacks a
reference to ‘next-gtk-webkit’ even though is invokes it:

--8<---------------cut here---------------start------------->8---
$ guix gc --references $(type -P next) | grep next-
/gnu/store/9d66xb8wvggsp0x9pxj61mzqy007978f-sbcl-next-1.1.0
/gnu/store/pqy064fw3vkfld6lw95vi0zavj19zvrc-sbcl-next-1.1.0-lib
$ ./pre-inst-env guix run next

WARNING: Setting locale failed.
  Check the following variables for correct values:
  LANG=en_US.utf8
Unhandled SIMPLE-ERROR in thread #<SB-THREAD:THREAD "main thread" RUNNING
                                    {10005885B3}>:

--8<---------------cut here---------------end--------------->8---

(Here ‘guix run’ runs ‘next’ in a container with exactly the closure of
‘next’, nothing more, and the ‘next’ binary is grafted.)

So the problem looks a lot like that this GCC issue we fixed a while
back: <https://bugs.gnu.org/24703>.

Looking at the ‘sbcl-next’ package, the reference to ‘next-gtk-webkit’
is inserted in gtk-webkit.lisp:

--8<---------------cut here---------------start------------->8---
(defvar *gtk-webkit-command* "next-gtk-webkit"
  "Path to the GTK-Webkit platform port executable.")
--8<---------------cut here---------------end--------------->8---

Through hexl-mode on the ‘next’ binary, we can find that reference:

Apparently this string literal is stored as UTF-32 (UCS-4) or similar,
which prevents the reference scanner and the grafting code from finding
it, and problems ensue.  :-)

Pierre, Andy: is there any way to tell SBCL to store this literal as
ASCII/UTF-8?  That would be an easy fix, though we should discuss the
pros and cons and whether to enable that globally.

Thanks in advance!

Ludo’.
