Same problem here.

Please fix it.

GCC 4.3.0 has many bugs and it's know to miscompile the kernel code. Even if this compilation problem would be fixed the kernel won't boot under XEN anyway (already tried). 4.3.1 addressed some of these errors already. Check it out and report your results.
Comment 3 Rafał Mużyło 2008-06-10 09:32:25 UTC
While I don't understand what are exactly xen-sources for,
comment 2 is (probably) FUD.
There were certain fixes added to gentoo-sources-2.6.24-r4 that fixed the problem reported here (cld issue was fixed in vanilla 2.6.24.4, this build issue in 2.6.24.5).
It simply looks like xen-sources should be updated.
Comment 4 Salvatore Cristofaro 2008-06-10 11:59:10 UTC
The patch you are speaking about, it's (probably) the same that i already posted.
The problem it's in the xen patch instead. 

At this moment, there is not 2.6.24.x xen patched kernel working as Dom0.
The last version for xen dom0 it's the 2.6.22, not in portage yet.

Still no work with gcc 4.3.1, without patches...

Does the problem is related to xen patches?

xen-sources-2.6.21 patch for compile with gcc 4.3.x

I found this patch from the Xen Mailing List:
http://xen.markmail.org/message/3b7ubksiqmdspvtv?q=gcc+4%2E3#query:gcc%204.3+page:1+mid:jr37gfbmdgqqgfka+state:results

Now kernel compile fine.
I will make some test first then to apply fixed to this bug.

Not that it needs to be confirmed again, but I see the same failure (and success post-patch) with gcc "Gentoo 4.3.1 p1.0" on i686.
Comment 12 Ryan Hill (RETIRED) gentoo-dev 2008-11-19 07:19:28 UTC
ping?
Comment 13 Robert Buchholz (RETIRED) gentoo-dev 2008-11-19 12:37:01 UTC
those sources are not maintained anymore and p.masked. Closing this bug.
Please reopen if you have problems with xen-sources 2.6.18.
