  Makes absolutely no sense. xmlCleanupParser() is a library wide
memory deallocation, you should not call it while you had document allocated
since they could now point to freed area (example predefined entities).
I think your methodology of test is wrong, and the programming way of
trying anything until it seems to work to not be better. Read the doc
dor xmlCleanupParser() it is very clear you should not do this.
