[Bug:1.8] block.call$B$NCf$G(Bsuper$B$G$-$J$$(B

r25975の変更

• eval.c (proc_invoke): unbound block created by define_method
  cannot call super. [ruby-core:26984]

から、以下のようにすると

NoMethodError: super called outside of method

という例外が発生するようになりました。

class Parent
def run
:parent_run
end
end

class Child < Parent
def run
callback do
super
end
end

def callback(&block)
  block.call
end

end

Child.new.run # -> 例外

Child#callbackの中のblock.callをyieldにすると例外は起きなく
なります。

SubjectにBugをつけてしまったのですが、そもそもこれはBugではな
く意図した変更なのでしょうか？

とりあえず、テストケースは添付しておきます。

余談ですが、この間リリースされたRuby 1.8.7にもこの変更が入っ
ていたため、Rabbitが動かなくなり、この違いに気づきました。
