It seems that ruby 1.9.2 and later doesn't like exception handling in 
`at_exit` blocks and resets the exit code to 0.

Here is an example:

    #!/usr/bin/ruby

    at_exit do
      raise "X" rescue nil
    end

    at_exit do
      nil
    end

    at_exit do
      exit 1
    end

    at_exit do
      exit 2
    end

Results:

[Ruby 1.9 - Bug #5218] at_exit bug with exception handling

Issue #5218 has been updated by Edgars Beigarts.


To fix ruby 1.9 I came up with this workaround:

if defined?(RUBY_ENGINE) && RUBY_ENGINE == "ruby" && RUBY_VERSION >= 
"1.9"
  module Kernel
    alias :__at_exit :at_exit
    def at_exit(&block)
      __at_exit do
        exit_status = $!.status if $!.is_a?(SystemExit)
        block.call
        exit exit_status if exit_status
      end
    end
  end
end
