Fixed In Version:	coreutils-8.22-13.el7	Doc Type:	Bug Fix
Doc Text:	Cause: Coreutils i18n downstream patch had several implementation bugs. Consequence: This was causing crashes and wrong functionality of e.g. sort utility in utf-8 locales. C locales were never affected. Fix: Buffer overflows and wrong handling of keys and fields in sorting was fixed. Result: Even when sorting with utf-8 locales, sort works fine with multiple sorting keys and fields.	Story Points:	---

Description Ondrej Vasik 2014-10-01 08:49:12 UTC

+++ This bug was initially created as a clone of Bug #1146185 +++

Description of problem:
When sorting on one of several fields and using e.g. the en_US.utf8 locale, "sort" looks at more than the specified keys when sorting.

Version-Release number of selected component (if applicable):
coreutils-8.21-20.fc20.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. printf 'a b!x\na-b-c!x\n' | LANG=en_US.utf8 ltrace -e strcoll sort -s --debug -k1,1 -t!

Actual results:
sort: using ‘en_US.utf8’ sorting rules
sort->strcoll("a b!x", "a-b-c!x")                = 21
a-b-c!x
_____
a b!x
___
+++ exited (status 0) +++


Expected results:
sort: using ‘en_US.utf8’ sorting rules
sort->strcoll("a b", "a-b-c")                    = -1
a b!x
___
a-b-c!x
_____
+++ exited (status 0) +++

(That is, strcoll only called on the key, not the whole string, and the output in the opposite order.)

Additional info:
This is shortened version of a bug report I filed upstreams: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18540  It appears this bug is not present upstreams, but actually introduced in the Fedora packaging.
