Well, it's potentially a glibc problem. But I haven't fully ruled out
other packages yet. All I know is that it works with an older chroot
which has glibc-2.19. But it may be related to gcc as well, no idea.

But wouldn't it then show in the old chroot sometimes as well? It never
shows there, just with the recent chroot.

It shouldn't. It's not necessary at all. Try bootstrapping with --variant=minimal.

Mmh, it doesn't work at the moment because I uploaded a patched glibc package
to "unreleased" and debootstrap doesn't support that. You need a patched
version of debootstrap to make this work.

Unless Gentoo modified debootstrap in some way, that shouldn't be a problem.
