Bug #1241: Segfault with Nokogiri 1.2.1 on Ruby 1.9.1p0

• Status: Third Party's Issue
• Assignee: -
• Target version: 1.9.1
• ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]

=begin
After installing a clean Ruby 1.9.1-p0 from Ruby-mswin32 (http://www.garbagecollect.jp/ruby/mswin32/en/), I installed Mechanize 0.9.1 with:
gem install mechanize
after which also installed Nokogiri 1.2.1.

Then, when I run irb, and type in require 'mechanize', I get a segfault on loading Nokogiri's native.so:

require 'nokogiri'
in irb, on Windows XP-32bit and Windows 7-32bit.

=begin
nokogiri's native.so from gem seems to be for ruby 1.8.
