I encountered segmentation fault when I used LibXML-ruby with Ruby 1.9.1.
My environment is as follows:
OS: Windows XP Professional SP2
Ruby: ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]
LibXml-ruby: 1.1.3

I can reproduce error just running ruby script which only require 'xml'.
I can run libxml-ruby successfully with ruby 1.8.6 and 1.8.7.

Following is the error message:

C:/ruby19/lib/ruby/gems/1.9.1/gems/libxml-ruby-1.1.3-x86-mswin32-60/lib/libxml_r
uby.so: [BUG] Segmentation fault

The binary gem of libxml-ruby is for 1.8, not 1.9.
Ask the distributor of the gem.

This is not a bug. The libxml-ruby gem that ships for windows is
compiled against 1.8.6, and will not work with 1.9. You need to
contact the libxml-ruby maintainers and get them to release a 1.9
compatible version.

It's a bug of rubygems, which installed incompatible binary.

Hello Nobu,

Actually there is a problem with RubyGems approach to gem versioning:

http://rubyforge.org/pipermail/rubygems-developers/2009-April/004522.html

This turned into what Aaron called "fat-binaries" approach, which I've
worked in rake-compiler project.
