This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

I think this needs to be a higher severity than just medium!

This is more than just case insensitivity. The severity needs to be upped. $ printf "%s\n" {a..z} {A..Z} | grep '[^A-Z]' a $ rpm -q grep grep-2.6.3-1.fc13.x86_64

Reopened, it still does not work in RU locale.
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'.

Same thing with --word-regexp grep --version grep (GNU grep) 2.16 cat rus-test Не стой столбом за правду жизни. стойлол! столбик конец файла grep -w стой rus-test Не стой столбом за правду жизни. стойлол! But there should be only one match!

Works fine in F23 btw
Seems broken again as an upstream issue: $ echo йцукен | grep -w кен йцукен Works fine for English text: $ echo qwerty | grep -w rty | wc -c 0 Seems not depending on locale (en_US.utf8 and uk_UA.utf8 are affected, at least). Can anybody reopen this?
I can reproduce with grep-3.1-9.fc30.x86_64 But it needs to be fixed upstream.
Is it related? http://savannah.gnu.org/bugs/?37600 http://savannah.gnu.org/bugs/?24452

Upstream bugs in Comment 20 are still open, but now the case in Comment 18 does not reproduce for me (seem fixed somehow).
