Forum: Ferret Possible bug when creating a Ferret::Search::Sort object?

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?

Hi,

this works fine for me with 0.11.6 with stock Ubuntu and Debian Ruby
versions:

ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux] (Ubuntu 7.10)
ruby 1.8.5 (2006-08-25) [x86_64-linux] (Debian 4.0 (stable))


irb(main):001:0> require 'ferret'
=> true
irb(main):002:0> Ferret::Search::Sort.new(
irb(main):003:1*       [
irb(main):004:2*           Ferret::Search::SortField::SCORE,
irb(main):005:2*           Ferret::Search::SortField::DOC_ID
irb(main):006:2>       ],
irb(main):007:1*       true
irb(main):008:1>   )
=> Sort[<SCORE>!, <DOC>!]
irb(main):009:0> Ferret::VERSION
=> "0.11.6"


Cheers,
Jens

I'm using Ferret 0.11.6 on Gentoo Linux:
ruby 1.8.6 (2007-09-24 patchlevel 111) [x86_64-linux]

So maybe this is a Ruby 1.8.6-p111 bug?
