のように2回目以降で結果が違うのが原因のようです。

直接crypt(2)を同じ引数で呼んでも同じ結果になります。

$ cat a.c
#include <stdio.h>
#include <unistd.h>

int main()
{
        printf("%s\n", crypt("", "\xE0\xA0"));
        printf("%s\n", crypt("", "\xE0\xA0"));
        printf("%s\n", crypt("", "\xE0\xA0"));
        return 0;
}
$ gcc a.c
$ ./a.out |LANG=C cat -v

M-`M- fT7zdRv9Y7A
