Date: Fri, 31 Aug 2007 10:43:26 -0700

Package: grep
Version: 2.5.3~dfsg-1
Severity: important

There is a regression in this grep: a "cat /proc/stat | grep -w cpu"
only shows the word "cpu" and not the whole line containing that word
(i.e. it behaves as if I had run "cat /proc/stat | grep -wo cpu").  That
makes "-w" pretty useless. grep-2.5.1.ds2-6 from Debian stable does not
have this bug.

  You're playing with everyone's nerves are you ? Don't you grok that
you are not reproducing the bug in the environment reported by every
single users ? It's pretty obvious the issue is with utf-8 locales, and
you're trying in one that isn't even a multi-byte one.


  I was pretty dismayed when you sent me a similar answer, I just can't
believe that you just handwave a "I can't reproduce it" to every single
user that has issues with the last grep release. Do you believe everyone
is just making it up to annoy you ?

The bug only happens (for me) with UTF-8 locale (massaged output below a
bit to compensate for the missing \n after the UTF-8 output)

% cat /proc/stat | env -i /bin/grep -w cpu
cpu  11736906 15928453 1355819 64884676 1101227 326476 32868 0

I am unable to confirm this bug. GNU grep 2.5.3 from ftp.gnu.org and from
Savannah CVS works fine with -w in that it does not imply -o. I tested
this on Mac OS X and Debian under different locales.

If you can reproduce this bug with the CVS or the release version, let me
know.

Cheers,

TAA
