Segmentation Fault when using Custom XPath functions (1.4.1, 1.4.3.1)

[juskoljo]

Hi,

First of all thanks for this wonderful gem! However I'm facing major issues when trying to use my custom XPath function called compare_value(@name, 'text'). Goal is to retrieve all nodes ('object') which contains certain attribute ('text', case insensitive string compare) and its (attributes/attribute/value) actual value meets the reg exp.

Script & XML to reproduce issue:
http://gist.github.com/579708

• Ubuntu 10.04
• libxml2 2.7.6
• gem versions used: 1.4.1 and 1.4.3.1
• Ruby 1.7.8 p72 and p249

BR,
Jussi Koljonen

Fixed a segfault when GC occurs during xpath handler argument marshalling. Closed by 0a1556a
