toralf, if you check the build dir, you should have two copies of each of those - could you upload a tarball (or two tarballs, whatever) with a folder for the stage2 copies, and another folder for the stage3 copies?

Unfortunately the build dir is a tmpfs - and a reproduce attempt was unsuccessful. I enhanced the tinderbox logic to keep the portage tmp dir if the first gcc upgrade fails.

Argh, attached to wrong bug report (although probable dup report). Sry.
