Hi!

I use the buildroot snapshot from 2008.08.05 and compile for a ARM
architecture. See the attached .config file.

I activated the gettext package and i18n support in the toolchain, as i need
localization support in shell scripts. These shell scripts generate some
webpages, that display their messages in different languages.

As soon as i set LC_ALL to de_DE or any other legal language code, gettext
segfaults:

# export LC_ALL=de_DE
# gettext "Hello"
Segmentation fault

But en_EN seems to be ok :

# export LC_ALL=en_EN
# gettext "Hello"
Hello#

As well as any random string:

# export LC_ALL=foo
# gettext "Hello"
Hello#

I 'ltrace'ed gettext and got the following output:

# export LC_ALL=de_DE
# ltrace gettext "Hello"
__uClibc_main(37544, 2, 0xbefb3dc4, 35696, 45824 <unfinished ...>
__errno_location()                               = 0x400b4470
getenv("TEXTDOMAIN")                             = NULL
getenv("TEXTDOMAINDIR")                          = NULL
strrchr("gettext", '/')                          = NULL
strncmp("gettext", "lt-", 3)                     = -5
setlocale(6, "" <unfinished ...>
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

It crashes in the function "setlocale" which schould be part of the uClibc, right?

A normal run looks like this, with LC_ALL empty:

# ltrace gettext hello

I did a 'make uclibc-menuconfig' and checked the localization options, 
everything needed seems to be activated.

Is this a configuration problem?
