It seems that /var/lib/portage/world is corrupt and contains NULL bytes.  You should probably check your filesystem for additional corruption.

[gentoo-user] odd emerge problem

[Adrian]

Greetings all;

Emerge is doing some odd things.  Most of the time it works, but when I
try to run 

emerge -pv world 

I get:
---------------------------------
\x02Mon Aug 21 19:47:13
\x02/usr/portage/distfiles/portage-snapshots
 root $  emerge -pv world

These are the packages that would be merged, in order:

----------------------------

emerge -pv system

works just fine.  I have been & currently am installing other things.
I've gotten the same (or a very similar) message when trying to install
or fetch some packages, but I can consistently reproduce this when I
try to do the emerge -pv world.  Or anything else with the 'world'.

As always, I am very thankful for any assistance or leads.

You were so correct.  
Problem solved.
I'll be checking the file system for corruption.
Thanks so much.

I was getting a lot of these a week or so ago. I also noted a fair
number of portage/emerge zombie processes showing up in top, and some
others that just hung for no good reason. A workaround was to make sure
no emerges were still running then 'killall emerge' and retry.

That worked. Meanwhile, since a portage update in the last few days the
bug hasn;t shown up again for me.
