I first compiled glibc-2.16.0 with gcc-4.4.7 w/o problems and then went on to compile gcc again which failed to compile. Indeed it's not possible to compile glibc-2.16.0 again as well.

Created attachment 330170 [details] gcc-config-logs.tar.bz2
And just adding to the obvious, I have already tried adding "-mno-avx" to my CFLAGS so I don't think this a dupe of #357287
Please attach the entire build log to this bug report.
Created attachment 330268 [details] build.log correct build log, got it wrong before.
I encountered this during the rebuild for the removal of the "nocxx" USE flag. As well as 4.4.7, this also affects gcc 4.3.6: /var/tmp/portage/sys-devel/gcc-4.3.6-r1/work/gcc-4.3.6/libgcc/../gcc/config/i386/linux-unwind.h: In function 'x86_fallback_frame_state': /var/tmp/portage/sys-devel/gcc-4.3.6-r1/work/gcc-4.3.6/libgcc/../gcc/config/i386/linux-unwind.h:142: error: field 'info' has incomplete type but gcc 4.5.4, 4.6.3, and 4.7.2 rebuilt fine. My system gcc is 4.6.3 and I do not have any problems rebuilding glibc-2.16
Maybe this bug is less important now or even obsolete, at least to me, because I kept 4.4.7 only for the sake of openvz-sources which ran in to kernel panic when compiled with a later version. However, since opening this bug I have upgraded to the latest openvz-sources-2.6.32.62.2 and compiled it to boot successfully with gcc-4.6.3, so my need for this bug to solve has sort of vanished. It may still needs to be solved in case there are other ebuilds having problem with later gcc, otherwise unless the build.log show something obvious, I would vote to close this bug as obsolete as there is a better version of gcc available and stable. By the way, I was later as well able to compile glibc-2.16.0 with gcc-4.4.7, initially it failed but another try yesterday succeeded and I never checked that error so closely so could possibly have been something else. It was though unmasking glibc-2.16.0 that lead to the gcc-4.4.7 failure, after glibc had been upgraded and compiled with it. I will keep my gcc-4.4.7 until this bug is closed, in case needed. I also have 4.5.4 as a backup so doesn't really need 4.4.7 any longer.
