Bug #11986: Segmentation fault
https://bugs.ruby-lang.org/issues/11986

* Author: Fabio Inguaggiato
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
I've got the attached segmentation fault every time I shut down a web app. The web app is made with Sinatra and supports WebSockets with faye-websocket gem. The app runs with Passenger in standalone mode. I've already tried more Ruby versions (2.1.1, 2.2.3, 2.2.4 and 2.3.0) and I've always got segmentation fault closing the web app. The server is Debian GNU/Linux 8.2, kernel version 4.1.5-x86_64.

This error always occur consistently, so I can do other tests if someone has suggestions. If necessary I can provide more information about the running environment.

This issue has been sent also to eventmachine gem issue tracker system.
