>Environment:

	The problem appears to exist both in FreeBSD 2.2.5-RELEASE and
	FreeBSD 3.0-CURRENT

>Description:

	The strxfrm() function always fill up all the supplied *dst
	space with THE SAME character IF supplied *src string is
	longer than 1 character AND current locale is not "C".

	The particular character that is filled in *dst seems to
	depend only on the first character of *src.

	This behaviour makes strxfrm() function useless for comapring
	strings that start with the same character.

	strcoll() function works fine.

>How-To-Repeat:

#include <iostream.h>
#include <string.h>
#include <locale.h>

int main() {

	/* any but C locale seems to produce the bug */
	setlocale(LC_ALL,"ru_SU.KOI8-R");

	char s1[50]="qasdf", s2[50]="qdfg", s3[50], s4[50];

	strxfrm(s3,s1,49);
	strxfrm(s4,s2,49);

	/* The following line prints 0 though strings aren't equal */
	cerr << strcmp(s3,s4) << endl;

	/* This reveals WHY strcmp() returned 0 */
	cerr << s3 << endl;
	cerr << s4 << endl;

	/* This shows that strcoll() still works fine */
	cerr << strcoll(s1,s2) << endl;

	return 0;
}
