What happens, if you do *not* sudo but log in as root and then
fetchnews?

There's said that there are "additional sanity checks" in glibc. So
either sudo or fetchnews are insane.

Since I do not have any problem or insanity in using fetchnews, I
suspect it's sudo or the combination of sudo and fetchnews.

I have installed version 2.0.0_alpha20060321 of leafnode. gcc is
installed in versions 3.3.6 and 3.4.6-r1, gcc-config says I'm using
3.4.6 (I suspect you also habe an installed 3.4.6, but did not switch
with gcc-config. Remember to fix_libtool_files.sh!)

Maybe I could risk a short look at how much traffic is on -user, but I
think itd be too much for my poor mailbox. I'm currently reading only
-user-de.

HTH,
