[Bug libc/5532] New: Not clear behaviour of function strerror_r

["ylalym at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

Program:

#define _REENTRANT
#include <string.h>
#include <stdio.h>

int main()
{
 char s[1024];
 strerror_r(1, s, 1024);
 printf("\ns = \"%s\" len = %d\n\n", s, strlen(s));
 return 0;
}

Save this program as a.c and a.cpp

> gcc a.c
> ./a.out

s = "Operation not permitted" len = 23

> g++ a.cpp
> ./a.out

s = "���ӷPÓ·hÕ?�Y���" len = 21

> icpc a.cpp
> ./a.out

s = "@���D���" len = 8
