ruby-core

Hi,
it seems I discovered a bug since I can get a reproducible segfault on different hardware when trying to use a freshly created rails application using a sqlite3 database running on a webrick. I didn't test with other db so I dont know if that comes from sqlite3-ruby gem. The following instructions triggers the problem on the two systems I tested them on:

using ruby 1.8.2, sqlite3-ruby 1.1.0 and rails 0.12.1 installed with rubygems, gcc 3.4.3, glibc 3.4.3 all on a linux 2.6 kernel

 > rails testapp
  [...]
 > cd testapp
 > cat << EOF > config/database.yml
development:
  adapter: sqlite3
  dbfile:  db/rails-devlopment.db

test:
  adapter: sqlite3
  dbfile:  db/rails-devlopment.db

production:
  adapter: sqlite3
  dbfile:  db/rails-devlopment.db
EOF
 > echo 'create table films (id integer AUTO_INCREMENT PRIMARY KEY, title varchar(255) NOT NULL);' | sqlite3 db/rails-development.db
 > script/generate model Film
  [...]
 > script/generate controller Films
  [...]
 > vim app/controllers/films_controller.rb
  [ add "scaffold :film" in FilmsController class ]
 > ruby script/server

I'm connecting to the server on http://myname:3000/films/list
and trying to add a film gives:
