Given the following code:
{{{
#! /usr/bin/ruby -w
class MyClass
def dup
super
end
end
a = MyClass.new
p a
b = a.dup
p b
}}}
I get this fatal exception using the Oct 24 nightly build of MacRuby:
{{{

}}}
The code works as expected when run with Ruby 1.8.7. It also works
without the overridden 'dup' method.
