please ignore the part about this being a workaround ;). While trying
this in the
actual code base, I noticed that it does not really help. Then I
realized that I was
doing the adoptNode() the wrong way around in the example, which certainly did
not have the intended effect as it resulted in a different output
document. The call
should actually read
    $doc->adoptNode($new_node);
instead of
    $doc2->adoptNode($node);

In the meantime, I quickly tried the test script on FreeBSD 9.3, with
Perl 5.18.4,
libxml2 2.9.2_2, p5-XML-LibXML 2.0118,1, but so far have not noticed
any crashes.

Best regards
