I've tested with libxml2-2.4.23 and XML::LibXML 1.53 on linux and it works 
just fine.

this looks suspicious as address: 0xabababab, as you have traced it. So it 
could be a bug in the ActiveState's perl or is it a standard one?

Though the good thing is that it happens on croak (something went wrong). So 
perhaps you can check why does it happen in first place. I'd at the above frame.
