Confirmed on upstream sbcl ml, debian'ers are also seeing fatal problems on
gcc-4.3-derived systems.

My most recent post to upstream ml:
"[Sbcl-devel] sbcl doesn't run on gcc-4.3 environment?"
http://sourceforge.net/mailarchive/forum.php?thread_name=fr3e81%242tj%241%40ger.gmane.org&forum_name=sbcl-devel

gcc43/kernel bug? sbcl devs pointed me to:
"GCC 4.3.0 exposes a kernel bug"  http://lwn.net/Articles/272048/
(I'm not currently an lwn subscriber, so can't access the article, yet).

Fix upstreamed:
http://marc.info/?l=git-commits-head&m=120492000901739&w=2

So, hopefully just a matter of time to see this.

-- Additional comment from davej on 2008-03-10 11:02 EST --
latest builds should have this.
If not, todays definitely will.

Thanks, I'll sync my rawhide lappy, and see how things go.

Comment 1 Rex Dieter 2008-04-25 17:25:09 UTC
sbcl/f9 builds in fedora buildsys using RHEL5 continue to fail,
http://koji.fedoraproject.org/koji/taskinfo?taskID=583155

I suspect they will continue to do so, until when/if the buildsys hosts' kernels
are patched.

Comment 2 Chuck Ebbert 2008-04-28 02:11:09 UTC
Is there no RHEL5 fix for this yet?
