   Ok. I've found this bug. It is really strange.
   Some pointers, allocated in such code:

   xmlInitParser();
   doc = xmlParseFile(xmlname);
   xmlCleanupParser();

   are freed after that in such code:

   xmlInitParser();
   result = xsltApplyStylesheet(xslt,doc);
   xmlCleanupParser();

   inside xsltApplyStylesheet().
   
   And in this moment memory manager was CHANGED already, because
   documents and stylesheets/processing memory pools are DIFFERENT!

   Stylesheet application is not READ-ONLY operation for input
   _document_ (not stylesheet, I know about stylesheet and _private
   members)!

   SHIT! WHY?!
   I understand, it is question for xslt gnome org, but is here any
   plans to change such STRANGE situation?
