Segmentation violation with a saved core (cmucl & clg)

Hi Espen,

I updated my clg to the latest CVS version yesterday (4 Mar 2009).
I saved a core file (with EXT:SAVE-LISP) after clg was compiled.
This core file will give an of segmentation violation upon startup.

Here are the steps to generate the error:

  1. In CMUCL (I'm using Snapshot 2008-11 (19E) on a Gentoo Linux machine):
       (asdf:oos 'asdf:load-op :gtk)
       (ext:save-lisp "clg-core")

  2. In UNIX shell, add the following symlinks:
       ln -s /.../clg/gffi/gffi-alien.so /usr/lib/gffi-alien.so
       ln -s /.../clg/glib/glib-preload.so /usr/lib/glib-preload.so
       ln -s /.../clg/glib/glib-alien.so /usr/lib/glib-alien.so
       ln -s /.../clg/cairo/cairo-alien.so /usr/lib/cairo-alien.so
       ln -s /.../clg/gio/gio-alien.so /usr/lib/gio-alien.so
       ln -s /.../clg/gdk/gdk-alien.so /usr/lib/gdk-alien.so
       ln -s /.../clg/gtk/gtk-alien.so /usr/lib/gtk-alien.so
     where "..." is the path leading to the clg source directory.

  3. At the shell prompt, type 
       lisp -core clg-core
     and get the following:
