I can reproduce this bug with 2.5.4 grep -V GNU grep 2.5.4 echo 'foo bar' | grep '^foo\W'; echo $? foo bar 0 echo 'foo bar' | grep -i '^foo\W'; echo $? foo bar 0 echo 'foo bar' | LANG=C grep -i '^foo\W'; echo $? foo bar 0 echo 'foo bar' | LANG=en_AU grep -i '^foo\W'; echo $? foo bar 0 echo 'foo bar' | LANG=en_AU.UTF-8 grep -i '^foo\W'; echo $? 1 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
