>Release: FreeBSD 3.0-CURRENT i386
>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;
