Description

$ ruby-trunk -v ruby 1.9.0 (2008-08-21 revision 18753) [powerpc-darwin9.4.0] 

の環境でtest_str_crypt(TestM17NComb)がFailureになります。

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- X8NBuQ4l6uQ M-`M- fT7zdRv9Y7A M-`M- fT7zdRv9Y7A
