Compiling gentoo-sources-3.5.3 and nvidia-drivers-304.43 with gcc-4.7.1 breaks gnome-session-3.4. Starting gnome I get the fail whale. Nothing special in the logs. Only dmesg: http://bpaste.net/show/44430/
It works with gcc-4.6.3
Problem seems to be related to something else. Today it was broken again until i added nouveau to VIDEO_CARDS again. Although I still use the nvidia driver (not even enabled nouveau in the kernel).
