Subject: [ruby-core:28132] [Bug #2729] `unexpected break' occurs when a proc is called in ensure

Bug #2729: `unexpected break' occurs when a proc is called in ensure
http://redmine.ruby-lang.org/issues/show/2729

Author: Nobuyoshi Nakada
Status: Open, Priority: Normal
Category: core, Target version: 1.9.x
ruby -v: ruby 1.9.2dev (2010-02-10 trunk 26629) [x86_64-darwin9.0]

Reproducing code:

  class Bug
    include Enumerable
    def each
      begin
        yield :foo
      ensure
        proc {}.call
      end
    end
  end
  e = Bug.new
  p e.detect{true}   # => :foo
  p e.any?{true}     # => true
  p e.all?{false}    # => false
  p e.include?(:foo) # => true

All work expectedly if no Proc#call, but all occurs `unexpected break' with it.
