facter -p segfaults with facts that call open-uri.open

Puppet Version: 6.0.9
Facter Version: 3.12.4 (commit ce9452fd2d15ed91eed9b8cc7823af783c9275a8)
OS Name/Version: Windows 2012

This custom fact succeeds on Linux but segfaults on Windows ... but only when calling facter -p not with puppet facts or puppet agent -t

require 'open-uri'

require 'json'

require 'timeout'

Facter.add('test') do

  response = nil

  begin

    url = 'https://api.ipify.org?format=json'

    Timeout::timeout(4) do

      response = open(url).read

    end

  rescue

    nil

  end

  if !response.to_s.empty?

    result = JSON.parse(response)

    setcode do

      result['ip']

    end

  end

end

(Same segfault occurs if you use Net::HTTP.get(URI.parse('https://api.ipify.org?format=json')) instead of open(url).read)

Result attached.
