I broke my gentoo with gcc 4.1

I finished emerging gcc 4.1 on my old computer and I started a emerge -e system && emerge -e world

It died on bash and pretty much screwed up everything

Now the computer fails on the mount command and if I chroot into the drive from a boot cd everything segfaults.

Any ideas on how I can bring back enough functionality to fix stuff from a boot cd. Like vi and emerge?

In this case you should think about reinstalling the OS from scratch.

Looks like a hardware crach to me. Reboot and run emerge --resume.
Edit: You may want to downclock it a bit to avoid this happening again.

It's not a hardware problem. Definatly software.

I think I forgot to rebuild the tool chain before doing emerge -e system.

I need a way to copy a working emerge binary and use it to fix my system.

I don't want to completely reinstall because I have cvs repositories and other code on the machine.

Really i would suggest booting a livecd, burning what you absolutely need and the config files for big things like xorg then rebooting and taking it as a lession to keep backups of your system if your gonna use unstable or testing things.

As long as you were safe enough to put you /home on another partition, you can reuse it.

Basically I'm an idiot for upgrading from 3.3 to 3.45 to 4.1 in one session. 4.1 wouldn't compile with 3.3

I'm actually making some progress trying to fix the problem tho. It turns out when using the live cd and chrooting it will execute one command at a time even after it segfaults. So i switched back to gcc 3.3 and trying to undo the damage done.

I have tried install gcc 4.0.2 as default compiler and also glibc 2.4, but It was a fresh stage1 install. First I emerged gcc --nodeps, then gcc and at the end gcc. Next thing was making bootstrap. And there wasn't any segfutls at all, exept my efforts to use prelink
