Luca, Thanks for your quick reply. I've tracked down the fixed applied in the sbcl cvs for this specific issue. The relevant messages to sbcl-commit are here for x86: http://sourceforge.net/mailarchive/forum.php?thread_name=E1KOy9Y-0006Iv-Uh%40sc8-pr-cvs8.sourceforge.net&forum_name=sbcl-commits And here for amd64: http://sourceforge.net/mailarchive/forum.php?thread_name=E1KOy9Z-0006Iy-1x%40sc8-pr-cvs8.sourceforge.net&forum_name=sbcl-commits The following patch resolves the issue for me on x86 but I haven't tested it on amd64.
