fold/glibc issue on x86_64

[Andreas Radke]

i got a bugreport from one ArchLinux x86_64 user : 

 http://bugs.archlinux.org/task/5365

Calling fold with 2 files ends up with a glibc hickup:

address@hidden ~]$ fold ~/.bashrc ~/.bash_profile 
alias ls='ls --color=auto'
PS1='address@hidden \W]\$ '

test -n "$DISPLAY" && export TERM=xterm-color

export CVS_RSH=ssh
. $HOME/.bashrc

address@hidden ~]$ fold --version
fold (GNU coreutils) 6.7

glibc is 2.5


Any idea?
