[bug-libunistring] Re: GNU libunistring 0.9.2 released

Hi Bruno,

On x86_64-linux-gnu with glibc 2.9 ‘test-localename’ segfaults for me:

Could it be that there’s something fishy specifically with
‘no_NO.UTF-8’?  See:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (setlocale LC_ALL "no_NO.UTF-8")
ERROR: In procedure setlocale:
ERROR: Invalid argument
scheme@(guile-user)> (setlocale LC_ALL "no_NO")
$1 = "no_NO"
scheme@(guile-user)> (setlocale LC_ALL "fr_FR.UTF-8")
$2 = "fr_FR.UTF-8"
scheme@(guile-user)> (setlocale LC_ALL "de_DE.UTF-8")
$3 = "de_DE.UTF-8"
scheme@(guile-user)> (setlocale LC_ALL "en_US.UTF-8")
$4 = "en_US.UTF-8"

Thanks,
