           Summary: setlocale() fails if LC_CTYPE is set to Turkish locale

              Type: ---

+++ This bug was initially created as a clone of Bug #726536 +++

Description of problem:

If the current locale is Turkish, setting a new locale fails if
the locale contains an 'I'.

Steps to Reproduce:

Compile and run:

#include <stdio.h>
#include <locale.h>
int
main(void)
{
    char *s;
    printf("%s\n", setlocale(LC_CTYPE, "tr_TR"));
    printf("%s\n", setlocale(LC_CTYPE, NULL));
    s = setlocale(LC_CTYPE, "tr_TR.ISO8859-9");
    printf("%s\n", s ? s : "null");
    return 0;
}

Actual results:

[stefan at fedora-14-amd64 ~]$ ./xxx 
tr_TR
tr_TR
null

Expected results:

tr_TR
tr_TR
tr_TR.ISO8859-9

Additional info:

My guess is that somewhere tolower() fails to convert the 'I'
to a proper lowercase 'i' if LC_CTYPE is Turkish.

This issue currently causes failures in the Fedora buildbot for

The test case works with libc-2.11.1:

   Ubuntu Lucid (libc-2.11.1), OpenSUSE (libc-2.11.1)

But not with:

   Fedora 14 (libc-2.13), Fedora 12 ( libc-2.11.2), Debian lenny (libc-2.7),
Gentoo (libc-2.13-r2)

If this is a regression in glibc, perhaps the priority should be
raised (or set).

Package glibc-2.14.90-5:
* should fix your issue,
* was pushed to the Fedora 16 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing glibc-2.14.90-5'
as soon as you are able to.
Please go to the following url:

Since the (automated) message asked me to test: Yes, of course I could,
but all download links for Fedora-16 pre-release still point to
Fedora-15-beta:

http://fedoraproject.org/get-prerelease.html

Is there an easy way (preferably a network install iso) to get Fedora-16 alpha?
