Since you have a multithreaded scenario, there were probably still
some docs around in some threads while an other thread called
xmlCleanupParser() and killed some data the docs were using. The
last line applies in multithreaded scenarios to _all_ docs; so if
you free all docs before a call to xmlCleanupParser() then you
might have a chance to survive. Just call it once at the end of
your app; plus call xmlInitParser() at the beginning of your
multithreaded app:
