I found that this bug is releated with rb_w32_write_console function.
Here is a possible patch.

This issue was solved with changeset r30412.
Heesob, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

I think r30412 is incomplete.

After applying r30412, while the second case is fixed, the first case is still exist.

I'm not the manager of ruby servers, so this is a mere guess,
the power failure and cutting the line have occured in the
region where the servers exist becase uf the heavy snow
of last week.
Unfortunately, all Japanese are on vacation of the new year,
so time is expected to be taken for restoration.
I guess that it will take more several days for restoration.
