It was. I downgraded all packages installed in the sid chroots of io
and asdfasdf which are built of the eglibc source package to version
2.11.2-13 (last 2.11 version which has been uploaded to unstable) from
snapshot.d.o and "dchroot sid" works fine again.
So until the real source of this problem (gcc-4.6 may be possible,
too) is found, I suggest to keep those packages on 2.11.2-13 in the
sid chroots of the kfreebsd porterboxes.
