Bug #11884: Psych.load broken for OpenStruct in Ruby 2.3.0
https://bugs.ruby-lang.org/issues/11884#change-57807

* Author: Kai Kuchenbecker
* Status: Closed
* Priority: Normal
* Assignee: Marc-Andre Lafortune
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]
* Backport: 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONE
----------------------------------------
Deserialising an OpenStruct through Psych::load results in a nil error since OpenStruct now has a respond_to_missing? method whose implementation references OpenStruct's @table instance variable.

To reproduce this issue simply use Psych to dump an OpenStruct and then load it again via Psych::load. I attached an example script that does exactly this. I have also attached the error output I get when running this script.

I'm not sure whether to assign marcandre or tenderlove... Please tell me if you need any further information.

Best regards,
Kai
