Comment:

 MacRuby still crashes when following code runs. Sorry X(

 {{{
 #!ruby
 String.send :initialize_copy, Fixnum
 Object.send :initialize_copy, String
 }}}

 Result:
 {{{
 $ macruby tt.rb
 Assertion failed: (type != 0), function rb_objc_type, file class.c, line
 1344.
 zsh: abort      macruby tt.rb
 }}}

 BackTrace:
