Core image and gl bindings

[R Alemi]

Dear List Members,
I need to use opengl with cmucl, and I have installed the cmucl-xlib-and-gl
extensions
provided by Knut Arild Erstad. it works fine, but when I save a core image
with
extensions:save-lisp, I get a segmentation error when I try to recall the
image.
Has anyone had this problem, or know how to solve it?
Regards,
Balto
