Description

=begin
I am trying to process tweets on engineyard for a rails app and constantly get segmentation faults, seemingly at random. The core and trace are below:

require '../config/environment'

Process.daemon true, false #daemonize me

if Rails.env == "production"
logger = Logger.new "/data/cloudable/current/log/processtweets.log"
logger.formatter = Logger::Formatter.new
else
logger = Logger.new "../log/process
tweets.log"
logger.formatter = Logger::Formatter.new
end

while true

tweets = Tweet.where(:processed => false)

tweets.each do |tweet|
  user = User.where(:twitter_uid => "#{tweet.user_id}").first # should be unique

  if user
    h = {:text => tweet.text, :id => tweet.tweet_id, :created_at => tweet.created_at,
         :url => tweet.urls.first}

    tweet.processed = true if TwitterJob.find_or_create user, h
    tweet.save!

    logger.info "Processed tweet %d" % tweet.tweet_id
  end
end

logger.info "Waiting to poll for new tweets"
sleep 5 # wait to poll for new unprocessed tweets

end

It's been quite a long time for this bug. Has it been tried on a newer Ruby? Is there any way to get a full reproduction, possibly without Rails?
