Subject: bug#18056: Coreutils 8.23 test-localename failure
Date: Sun, 20 Jul 2014 01:48:36 +0200

[Message part 1 (text/plain, inline)]

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
Name           : glibc
Version        : 2.19-5
Description    : GNU C Library
Architecture   : x86_64
[ ... ]
Build Date     : 2014-05-16T10:15:30 CEST
Install Date   : 2014-05-30T16:11:30 CEST

Thanks,
Henrik
