Hi.
I tested on OSX 10.4.11 with LibXML 2.7.2 from Darwin ports,
but just works fine.
Validation error printed same as your Ubuntsu one,
no segmentation fault.
This might be Leopard or LibXML2 issue.
Which LibXML version does you use ?
It can be given by LibXML::XML::LIBXML_VERSION.
In addition, validate_schema's callback seems not work currently.
Though LibXML2 has error call back API on Schema validation,
ruby-libxml also use it, but never invoked.
It would be LibXML2 bug.
You can use global error handler to
capture validation errors, set by XML::Error#set_handler.
