Today I have upgraded glibc on my multilib amd64 system from 2.16.0 up to 2.17. All 32 bit applications (e.g. skype and wine running win32 binaries) become to crash with segfault after the upgrade. Fortunately I have succeed to downgrade to 2.16.0. Reproducible: Always
What about to append more info? The exact segfault message and emerge --info I would say? For me on ~amd64 with glibc-2.17 compiled with USE +nscd by gcc-4.8.0 (LTO in use) Skype (4.1.0.20) works fine. Dtto for wine powered MyPhoneExplorer 1.8.4 for example. emerge --info wine Portage 2.2.0_alpha170 (default/linux/amd64/13.0/desktop/kde, gcc-4.8.0, glibc-2.17, 3.8.3-gentoo x86_64)

please post the output from doing: echo 'main(){puts("HELLO");}' > test.c gcc -m32 test.c ./a.out ldd a.out
Fortunately I have downgraded to glibc-2.16.0. So perhaps someone will have similar problems.
