Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ 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.
