Hi all,
Currently we're building a Rails application that uses libxml-ruby
(1.1.3) to parse some documents and loop over its contents with xpath
expressions.
When running the application with Ruby 1.8.7-p72, everything works
flawlessly. With Ruby 1.9.1-p0, however, we get frequent double-linked
list errors, like the one below.
Is this is a known issue? If not, some pointers that may help us
isolate the issue would be very welcome. Thank you!
