Subclasses of HashWithIndifferentAccess dup the wrong class

Reported by Steve Richert | September 28th, 2010 @ 03:56 PM

There are two instances of HashWithIndifferentAccess being named explicitly in its own class. No bug there, but if a new class is created that inherits from HashWithIndifferentAccess, the new_from_hash_copying_default class method and the dup instance method incorrectly return an instance of HashWithIndifferentAccess rather than the newly-created class.

class FooHash < HashWithIndifferentAccess

foo = # => {}
foo.class         # => FooHash
bar = foo.dup     # => {}
bar.class         # => HashWithIndifferentAccess
