Subject: xpath segfault
Download (untitled) / with headers
text/plain 483b
When I try to treat a DocumentFragment as a real Document node, and use xpath like '/whatever', I get a segfault. I'm not sure whether I should get the expected results (would be very convenient if it worked), but I don't think XML::LibXML should segfault. I attached a little script that demonstrates that travelling up the tree yourself ends correctly because the DocumentFragment has no parent node, but trying to use an xpath expression that would need to do the same segfaults.

Hi, this seems to be fixed since I can't reproduce the segfault with neither latest SVN version nor the latest developer's release 1.69_2; valgrind doesn't report any problem with your testcase either. And yes, you can't expect /anything to match on a non-document node. -- Petr Show quoted text
