Public bug reported:

While debugging an old Ruby script for determing the Internet connection
status (online vs offline), I found that running exec from Ruby would
crash Unity.

Steps to reproduce:

1. wget https://raw.githubusercontent.com/mcandre/mcandre/95350df18b982f455d49eca739f2e1ee42da75f4/ruby/webshout.rb
2. emacs
3. M-x shell
4. ruby webshout.rb

In particular, it seems that the line:

exec 'say You are now online.'

(which I've since corrected to use system instead of exec)

Attempts to replace the ruby process for webshout.rb with a GNUStep say
process. But something messes up, and Unity crashes.

System:

$ specs ruby emacs unity os
