I Just tried compiling and testing the 8.22 release, in order to do a comparison. But the test failed in the exact same way.

I also did tests on a similar but yet different arch linux installation at work, with the exact same results.

When compiling coreutils 8.22 on 2014-03-14 the tests succeeded. So whatever changed must be outside of coreutils.

One thing I noticed is that locale.h from the gnulib has the line:

#define setlocale rpl_setlocale

which doesn't seem to come into play (as it is my system's setlocale which is called from the test).

I have noticed that systemd has a localectl function, but doesn't list any changed behavior w.r.t. locales and environment variables, however, could systemd be the culprit?

Again, thanks.

I'm a bit rusty at gdb, but here's what I've been able to find:

I compiled coreutils with -ggdb3 and was able to see, that the test called gl_locale_name_posix, which used my systems current setlocale (do debugging symbols):

Breakpoint 5, 0x00007ffff7a582b4 in setlocale () from /usr/lib/libc.so.6
(gdb) step
Single stepping until exit from function setlocale,
which has no line number information.

gl_locale_name_posix (category=5, categoryname=0x4035f3 "LC_MESSAGES") at localename.c:2704
2704 }
(gdb)
gl_locale_name (category=5, categoryname=0x4035f3 "LC_MESSAGES") at localename.c:2854

2854 if (retval != NULL)
(gdb)
2855 return retval;
(gdb)
2858 }

(gdb)
test-localename.c:86: assertion 'strcmp (gl_locale_name (LC_MESSAGES, "LC_MESSAGES"), gl_locale_name_default ()) == 0' failed

retval from setlocale is:

(gdb) p retval
$11 = 0x606f00 "en_US.UTF-8"

So I'm unsure what to do next?

My GNU libc version is:
% pacman -Qi glibc

Thanks, since LC_MESSAGES is supposed to be unset at that point, gl_locale_name appears to be the culprit. Can you use GDB to figure out why it's returning "en_US.UTF-8"? You may need to recompile with "gcc -O0 -g3" to get decent debugging output. Or, if you can't use GDB, just put in printf statements.
