There it was marked as INVALID, because the source of the problem was determined as the Gentoo multilib setup. In the GCC-Bug there is a possible patch, but I can't see that patch being included in gcc, it looks like it would make much more sense in the gentoo patchset. I also tried to find out more why this breaks, here is what I noticed: It breaks, because fixincludes from gcc thinks the gentoo stdio.h is broken and needs fixing. But that fix is a rather harmless wrapper, that should normaly just be ignored. But: This wrapper prevents stdio.h from being included twice, and that is just what will happen with the failing .c file. I modified the "fixed" stdio.h to output a warning each time it is included and it shows the following output: In file included from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/cstdio:50, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/char_traits.h:48, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/string:47, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/locale_classes.h:47, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/locale:46, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/gcc-4.3-20070831/libstdc++-v3/src/codecvt.cc:30: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/./gcc/include-fixed/stdio.h:13:2: warning: #warning bla In file included from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/cstdio:50, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/ios_base.h:49, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/locale_facets.h:50, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/locale:47, from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/gcc-4.3-20070831/libstdc++-v3/src/codecvt.cc:30: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20070831/work/build/./gcc/include-fixed/stdio.h:13:2: warning: #warning bla The when the normal gcc build includes stdio.h a second time it will be skipped because of the fixinclude-fix and so the definitions of ::fpos_t etc. will be missing in one namespace. So I am opening this bug to ask the toolchain maintainer, if the fix from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30915 (or something similar that prevents fixincludes from touching the gentoo-multilib-stdio.h) can be included in the gcc-4.3-ebuilds, or if I should file a bug in the gcc bugzilla that they fix the wrapper that fixinclude inserts.
no idea why Jakub is unable to properly sort bugs
I've been seeing this bug with some crossdev builds.
Since around october I'm no longer seeing this bug on native builds. (I did not try any crosscompiles) Instead is later failed when building the precompiled header stdc++.h. It seems to generate borken definitions for the builtin constants __DBL_MAX__, __DBL_DENORM_MIN__ and __LDBL_MAX__. I did not report this, as the system I was trying to build the GCC-4.3 was using -ffast-math and that looked related. But after not even getting this fixed by rebuilding glibc, gmp and mpfr with different gccs I finally tried this on my stable amd64 system, where I never used -ffast-math. The error happend there too, so this doesn't seemed to relate to this (bad) flag. error output from the stable amd64 system: make[4]: Entering directory `/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-li nux-gnu/libstdc++-v3/include' if [ ! -d "./x86_64-pc-linux-gnu/bits/stdc++.h.gch" ]; then \ mkdir -p ./x86_64-pc-linux-gnu/bits/stdc++.h.gch; \ fi; \ /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/./gcc/xgcc -shared-libgcc -B/var/ tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/./gcc -nostdinc++ -L/var/tmp/portage/sys-devel /gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/src -L/var/tmp/portage/sys-devel/g cc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs -B/usr/x86_64-pc-linux-gnu /bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc -linux-gnu/sys-include -Winvalid-pch -x c++-header -pipe -march=athlon64 -O2 -D_GNU_SOURCE -I/var/tmp /portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/x86_64-p c-linux-gnu -I/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc ++-v3/include -I/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/gcc-4.3-20071221/libstdc++-v3/l ibsupc++ -O0 -g /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/gcc-4.3-20071221/libstdc++-v3/i nclude/precompiled/stdc++.h -o x86_64-pc-linux-gnu/bits/stdc++.h.gch/O0g.gch In file included from /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/gcc-4.3-20071221/libstdc+ +-v3/include/precompiled/stdc++.h:79: /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/ limits:1047: error: stray '\275' in program /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/ limits:1079: error: stray '\230' in program /var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-linux-gnu/libstdc++-v3/include/ limits:1104: error: stray '\232' in program make[4]: *** [x86_64-pc-linux-gnu/bits/stdc++.h.gch/O0g.gch] Error 1 make[4]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-lin ux-gnu/libstdc++-v3/include' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-lin ux-gnu/libstdc++-v3' make[2]: *** [all] Error 2 make[2]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build/x86_64-pc-lin ux-gnu/libstdc++-v3' make[1]: *** [all-target-libstdc++-v3] Error 2 make[1]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.0_alpha20071221/work/build' make: *** [profiledbootstrap] Error 2 * * ERROR: sys-devel/gcc-4.3.0_alpha20071221 failed.

Patch: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33992#c10 (Changes -O2 to -O1 in toolchain.eclass, I have not tested this myself, as I did not want to mess with this global eclass...)
Addendum: Because of a bug/feature in the flag-rewriting logic it is not necessary to patch toolchain.eclass. The rewrite "replace-flags -O? -O2" does not match -O which is identical to -O1. So changing -O3 to -O in make.conf has the same effect as the patch. Result: same error as in the initial report. So the O2-optimizer-bug only hid the gentoo multilib bug, that bug is still here. The still broken crosscompiles probably didn't hit this, because they can't use 'profiledbootstrap' and the other bug seems to break only(?) in the "use profile"-stage. (see toolchain.eclass, gcc_do_make() )
that's a completely different bug. this one is about the multilib patch.
As 4.3.0 is now in the tree, I thought I might test it, but I also run into this problem.

hrm, implicit eblit version ordering caused the wrong eblit to get picked up
cvs up and try again eh
woot!
i'd prefer to not revbump glibc yet again just to fix building a masked package on a subset of systems ... so if someone hits this answer, i say we tell them to rebuild glibc manually
(In reply to comment #10) > fixed in glibc-2.7-r2 why does gcc-4.3.0 not depend on >=sys-libs/glibc-2.7-r2 then?

Why is this bug marked as FIXED? Just look at the number of dupes recently and it is clear it OBVIOUSLY IS NOT. I ran into this _exact_ same build error today, as posted last September by Torsten. What is the fix for this issue? I know there is a patch for GCC that supposedly fixes this but it has *not* hit the portage tree, so what is going on? This is NOT fixed in glibc-2.7-r2, as I have that version emerged and upgrades from 4.2.4 to 4.3.1 are still broken on ~amd64-multilib! From reading this problem seems possibly related to this: http://bugs.gentoo.org/show_bug.cgi?id=201490
I compiled GCC 4.3.1 fine yesterday. I did an emerge --sync. After that when I went to update I noticed that GCC 4.3.1 wanted to pull in glibc 2.8 which. With that glibc installed, it builds fine. Try it out and let us know.

Now if GCC would only support a parallel build... Thanks, guys.
