If you've somehow installed the x86-mswin32-60 gem in your RubyInstaller environment, the gem linked against a different Ruby version (MSVCRT-RUBY18.DLL) than the 1.9.1 version you're running. This issue is a known cause of segfaults.

A very good XML library that uses libxml2 is Nokogiri http://nokogiri.org/

It is well documented, well maintained, and works well on multiple Ruby versions and implementations including Windows. I'd highly suggest the switch. Try it out with a simple "gem install nokogiri"

Hello,

This is highly likely a 3rd party issue.

Please open a Ticket on libxml-ruby project, provide the same code and the test XML data file (s.txt) that you mention but forgot to attach.

Thank you.
