Subject: [ruby-core:31804] [Bug #3722] segfault in rb_iterate (1.9.3, r29057)

Issue #3722 has been updated by Cezary Baginski.


I started tearing everything apart and came up with this minimal case:

 % ruby --version
ruby 1.9.3dev (2010-08-19 trunk 29056) [x86_64-linux]

 % cat fail.rb
require 'profile'
class A 
  include Enumerable

  def each
    yield 1
  end
end 
A.new.any? { true }

 % ruby fail.rb
fail.rb: [BUG] cfp consistency error - send
ruby 1.9.3dev (2010-08-19 trunk 29056) [x86_64-linux]
