Summary: unknown XPath function causes SEGV
Initial Comment:
A sample script:
require 'xml/libxml'
require 'tempfile'
xml = Tempfile.new("xxx")
xml.puts("<a/>")
xml.close
doc = XML::Document.file(xml.path)
begin
p doc.find("//*[name(.)=normalize_space(' a ')]")
rescue XML::XPath::InvalidPath
puts $!
puts $@
end
p doc.find("//*[name(.)=normalize-space(' a ')]")
Result:
xmlXPathCompOpEval: function normalize_space not found
Unregistered function
xmlXPathCompiledEval: 3 objects left on the stack.
Invalid XPath expression for this document

The error message remains the same, but this no longer causes a segfault. Test
case added.
