Some worker was crashed. It seems ruby interpreter's bug
or, a bug of test/unit/parallel.rb. try again without -j
option.

make: *** [yes-test-all] Error 1

と例外を吐いて落ちることがあります。require 'readline' で何故こうなるのかよくわかりませんが。
自分のr30939が原因なのかまだわかりませんが、近日中に調査して直します。

-jを付けなければ影響はありません。

Shota, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

• lib/test/unit/parallel.rb: Keep $stdin, $stdout before run testcase
  and restore after run. Because some test break $stdin, $stdout.
