[BusyBox] bug#1064: grep -v "^$" fails under mysterious circumstances

[David Douthitt]

Package: busybox
Version: 0.47

I'm using

grep -v "^$"

with one to four line files, and in one particular case it failed 
repeatedly (on a one line file).

At one time, I tried the following commands (all failed):

cat $file | grep "^$"
cat $file | grep ^$
grep ^$ $file
grep "^$" $file

Replace $file with a specific choice.

It happens frequently and almost every time.
