Description
=begin
Please backport r43334 to avoid SEGV when an undefined method is refined but the refinement is not used.
For example, the following program causes SEGV.
class Foo
def foo
end
undef foo
end
module FooExt
refine Foo do
def foo
end
end
end
begin
Foo.new.foo # or Foo.new.send(:foo)
end
=end
