  I just did that. There is a new configure option:
      --with-run-debug        add the runtime debugging module (off)
which is off by default and if turned on add tree checking each time
you free a document tree. The set of checkings done can be extended
(like verifying UTF-8 text node content and more structure checks),
but right now I have been focusing on the integration and fixing the
errors this raised. I fixed the problem found in libxml2 regression
tests, and still have to clean up the issues showing up in libxslt
regression tests. But this is already useful, I found a few hidden
but real issues in the libs already. Check the beginning of debugXML.c
in libxml2 to see the checking code. Patches for improvement of the
checking rules are welcome. I may open the API to allow checking of
a subtree too.
