I may have run across a bug in Ferret: if throws a segmentation fault when I try to create a Sort object using the default fields (SCORE and DOC\_ID), but setting reverse to true. Here’s the minimal example: #!/usr/bin/env ruby require ‘rubygems’ require ‘ferret’ Ferret::Search::Sort.new Ferret::Search::Sort.new( [ Ferret::Search::SortField::SCORE, Ferret::Search::SortField::DOC\_ID ], false ) Ferret::Search::Sort.new( [ Ferret::Search::SortField::SCORE\_REV, Ferret::Search::SortField::DOC\_ID\_REV ], false ) Ferret::Search::Sort.new( [ Ferret::Search::SortField::SCORE, Ferret::Search::SortField::DOC\_ID ], true ) You should get something like this when creating the last object: $ruby sort.rb sort.rb:23: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [x86\_64-linux] Aborted Again, this is with Ferret 0.11.6 in Linux. Is this a known problem that’s being worked on, or should I report it at the Trac tool on [ferret.davebalmain.com](http://ferret.davebalmain.com)? – Bira > **[Computaria Explícita](https://compexplicita.wordpress.com/)** > > I know it hurts.
