Subject: [ruby-core:71352] [Ruby trunk - Bug #11658] [Assigned] Segmentation fault with activeadmin test suite

Issue #11658 has been updated by Hiroshi SHIBATA.

Status changed from Open to Assigned

Can you install `nodejs` via apt?

I got another error related with r52332 at ubuntu 14.04

```
$ sudo apt install nodejs
$ cd activeadmin
$ bundle exec rake spec
(snip)
/data/dev/activeadmin/lib/active_admin/resource/action_items.rb:5:in `<module:ActiveAdmin>': No live threads left. Deadlock? (fatal)
	from /data/dev/activeadmin/lib/active_admin/resource/action_items.rb:3:in `<top (required)>'
```

above error happend by "ruby 2.3.0dev (2015-11-05 trunk 52458) [x86_64-linux]"

it works with Ruby 2.2.0(ruby 2.2.4p185 (2015-11-01 revision 52414) [x86_64-linux])

* Author: Hiroshi SHIBATA
* Status: Assigned
* Priority: Normal
* Assignee: Eric Wong
* ruby -v: ruby 2.3.0dev (2015-11-04 trunk 52452) [x86_64-darwin15]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
I detect causes of SEGV with Ruby 2.3.0 HEAD and activeadmin-1.0.0.pre2 after r52332.

Please try following instructions with ruby of r52332.

```sh
$ gem install bundler
$ git clone --branch v1.0.0.pre2 https://github.com/activeadmin/activeadmin
$ cd activeadmin
$ bundle exec rspec spec/unit/active_admin_spec.rb
```

this segv is happened at launching rails server too. I attached crash log.

Please investigate this.
