Different behaviour when including a module into Class in MacRuby vs Ruby 1.9.2

[james@…]

I'm seeing different behaviour when including a module into Class in MacRuby vs Ruby 1.9.2. This is a simplification of a problem I'm seeing running Mocha [1] tests in MacRuby. I seems to be specific to including the module into the Class class and not a user-defined class. It also doesn't seem to matter whether the class has already been defined or not.

$ rvm macruby
$ irb
macruby-0.6 > module X; def x; "x"; end; end
 => nil 
macruby-0.6 > class Class; include X; end
 => Class 
macruby-0.6 > Class.new.x
NoMethodError: undefined method `x' for #<Class:0x20020f960>
	from /Users/jamesmead/Code/mocha/(irb):3:in `<main>'

$ rvm 1.9.2
$ irb
ruby-1.9.2-preview1 > module X; def x; "x"; end; end
 => nil 
ruby-1.9.2-preview1 > class Class; include X; end
 => Class 
ruby-1.9.2-preview1 > Class.new.x
 => "x" 

$ rvm macruby
$ irb
macruby-0.6 > module X; def x; "x"; end; end
 => nil 
macruby-0.6 > class Y; include X; end
 => Y 
macruby-0.6 > Y.new.x
 => "x" 

$ rvm macruby
$ irb
macruby-0.6 > module X; def x; "x"; end; end
 => nil 
macruby-0.6 > class Y; end
 => nil 
macruby-0.6 > class Y; include X; end
 => Y 
macruby-0.6 > Y.new.x
 => "x"

I've just come across this commit [1] which looks like it adds a test for this problem to known_bugs.rb.

I'm now trying to investigate whether the problem has been fixed.
