Below is the test case which is failing for me on ruby 1.9.2dev (2010-04-02 trunk 27162) [i686-linux] but works on ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-linux]:

module Original
@@cvar = nil

def self.module_get_cvar
@@cvar
end

def function_get_cvar
@@cvar
end
end

Duped = Original.dup

Original.send(:class_variable_set, :@@cvar, "cvar in Original")
Duped.send(:class_variable_set, :@@cvar, "cvar in Duped")

class IncludesOriginal
include Original
end

class IncludesDuped
include Duped
end

puts IncludesOriginal.new.function_get_cvar # => cvar in Original
puts IncludesDuped.new.function_get_cvar # => cvar in Duped

puts Original.module_get_cvar # => cvar in Original

puts Duped.module_get_cvar # => 19_duped_module_class_variable_set_bug.rb:3: warning: class variable access from toplevel

Hi,

This is similar issue to [ruby-core:30313].
This issue is caused by ISeq#cref_stack instead of ISeq#klass.
This won't be fixed in 1.9.2.
