Now removing that from make.conf allowed me to compile the latest glibc which failed before (just as 2.10*, 2.11*) and still can't be build with this march. Hope is high the random segmentation faults (*** glibc detected *** [...]: invalid pointer) are gone now, to be sure i have globally activated the workaround by creating a /etc/env.d/00glibcfix which sets MALLOC_CHECK_=1 . The glibc git ebuild aswell as a log of a failing build is attached.

Created attachment 211054 [details] sys-libs/glibc-9999 git ebuild
btw just tested with mcpu=amdfam10 - fails aswell.
-march=barcelona (which is a synonym for amdfam10) works fine with glibc-2.10.1{,-r1} on my system. Did you try to reproduce the error with ccache being disabled?
-ccache doesn't help here.. obscure indeed is it..?
not sure why you think we would possibly care about build failures in current git tree. if the latest ebuilds _we put in the tree_ are failing, then post those logs. but we arent going to assist you in building latest git.
Ok i should have put the word 'including' before 'latest git' in the report title, but through careful reading you could have come to the conclusion that 2.10* and 2.11* are affected aswell. I just created the git ebuild to check if the issue has been fixed upstream, which it has not... attached it for possible inclusion in the tree - why not..
you mentioned failures in earlier versions but never stated what they were. you still need to post build logs of the relevant gcc versions -- i'm not going to look at live git versions. anyone using live/snapshot versions are fully expected to help in debugging any issues they might encounter.
Created attachment 211952 [details] sys-libs-glibc-2.10.1-r1-failed-build.log.bz2 should have posted this instead.
# clarifying bad bug title
your binutils/gcc appears to be screwed: checking for ld --no-whole-archive... no checking for gcc -fexceptions... no checking for __builtin_expect... no those should all be "yes". post the config.log from the build dir.

your toolchain is screwed. you'll have to figure out what exactly it's complaining about when it says: x86_64-pc-linux-gnu-gcc -O2 -fno-strict-aliasing -U_FORTIFY_SOURCE -ldl -Wl,-O1 -nostdlib -nostartfiles -fexceptions -o conftest conftest.c /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.2/../../../../x86_64-pc-linux-gnu/bin/ld: failed to set dynamic section sizes: No such file or directory collect2: ld returned 1 exit status
