I can't reproduce anything like this on Linux using these versions. However,
given that the stacktrace is almost etree-free (and no user code should have
run up to this point), could you report this on the libxml2 mailing list to
see if others can somehow give more context?

One more thing to test: are you using any other tools or libraries that depend
on libxml2 or libxslt in your code? It happens that other tools configure the
libraries differently, which can interfere with the way lxml uses them. OTOH,
if you are using a static Windows binary build, I doubt that this could pose
any problems...
