Summary: Calling parse() twice causes segfault
Initial Comment:
The following snipped of code is guaranteed to segfault:
require 'xml/libxml'
x=XML::Parser.string("<test>something</test>")
doc=x.parse
x.parse
If you run it using ruby on the command line it segfaults immediately, for eg.
$ ruby /tmp/segfault.rb
Or, if you copy paste it in irb, it segfaults as soon as you try to _exit_ irb.

Message:
This must be fixed.
class TC_XML_Parser2 < Test::Unit::TestCase
def test_double_parse
parser = XML::Parser.string("<test>something</test>")
doc = parser.parse
parser.parse
end
end
Result:
1) Error:
test_double_parse(TC_XML_Parser2):
XML::Parser::ParseError: Document didn't parse
C:\Development\msys\src\rlibxml\test\tc_xml_parser9.rb:8:in `parse'
C:\Development\msys\src\rlibxml\test\tc_xml_parser9.rb:8:in
`test_double_parse'
1 tests, 0 assertions, 0 failures, 1 errors
Entity: line 1: parser error : Document is empty
<test>something</test>
^
Program exited with code 1
Seems like reasonable behavior to me.
