Subject: [ruby-core:25172] [Bug #1648] Rational#div Raises NoMethodError for Invalid Argument

Issue #1648 has been updated by David Calavera.

File RUBY-1648_v2.patch added

The code of the spec is in spec/ruby/shared/rational/div.rb, but that's what fails:

ruby_bug "#1648", "1.8.7" do
    it "raises a TypeError if passed a non-numeric argument" do
      lambda { Rational(3, 4).div([]) }.should raise_error(TypeError)
    end
  end

I updated the patch to use respond_to?.
