OpenSSL::ASN1::ObjectId#== raises for OIDs without a known name

#!/usr/bin/env ruby

require "openssl"

oid = OpenSSL::ASN1::ObjectId.new("2.5.29.14")
pp oid
pp oid.long_name
pp oid.short_name
pp oid == oid

    from Untitled.rb:15:in `<main>'

when I would expect both oids to compare equal. I am unsure why OBJ_txt2nid is being used instead of comparing the underlying oid value

comparing the underlying oid value

It should be implemented this way (or by OBJ_cmp() on ASN1_OBJECT objects).

https://github.com/ruby/openssl/pull/792 will fix it.
