Locale problems with uclibc on arm

Hi,
I have run into a problem with building a scratchbox tool chain that
uses uClibc-0.9.28.3. The scratchbox version that I am using is 1.0. I
tried to build a scratchbox tool chain for arm with locale support where
it used pregenerated locale data. Though the compilation of the tool
chain was ok, when I ran the below test code the program terminated with
exit status 245.

#include <stdio.h>
#include <locale.h>

int main()
{
	char *locale = setlocale(LC_ALL,"en_US");
	if(locale)
		printf("locale set\n");
	else
		printf("locale not set\n");

	return 0;
}

The same code on using the locale "POSIX" works.

The code when compiled with a i386 toolchain using the same uclibc
version build in a similar way as arm toolchain gives the correct result
and does not terminate abruptly. I am not able to figure out as to what
is the problem is. 

I am having a similar problem even with 0.9.28.1 version of uclibc.

Any pointer as to what the problem might be. The uclibc config file is
as below
