* Author: Kenta USAMI
* Status: Open

* Assignee: 
* Category: 
* Target version: 
* ruby -v: ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]

----------------------------------------
`stack level too deep (SystemStackError)`が発生することを期待した。

~~~
% ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
% ruby -e"r = ->(n){ print %(#{n},); r.(n+1) }; r.(0)" > /tmp/foo_out 2>/tmp/foo_err
zsh: abort      ruby -e"r = ->(n){ print %(#{n},); r.(n+1) }; r.(0)" > /tmp/foo_out 2>/tmp/foo_err
~~~

(クラッシュレポートは添付)

なお、手元の環境では2.2.0devでは発生しない。
