Sorry but I won't take this bug without a full backtrace, considering I see this in your emerge --info: CFLAGS="-O3 -march=k8 -mno-tls-direct-seg-refs -mmmx -msse3 -pipe -fomit-frame-pointer -Wl,--enable-new-dtags -Wl,--sort-common -s" I don't usually reject bugs on basis of extreme flags environments, but this is not extreme, it's just silly, and shows you probably have no idea what those flags do. Either provide a full backtrace or rebuild your whole system with sane flags.
I'm getting the exact same symptom on both my amd64 and my x86 system after upgrading to sudo-1.7.1-r1, and I'm using sane CFLAGS. Downgrading to sudo-1.7.0 solves the problem. jon@careen ~ $emerge -pv sudo These are the packages that would be merged, in order: Calculating dependencies... done!

I've just posted bug #273785, which is the same bug as this one but hopefully will be resolved in some fashion other than INVALID.
I just commented on bug #273785 - in my case the segfault disappears when disabling the following pam_mount line in /etc/pam.d/system-auth: session optional pam_mount.so I don't know whether this is a pam_mount or a sudo bug. A similar issue has shown to be a sudo bug a year ago: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=462445#53
