  The problem probably lay out at the level where xmlSAXParseFile()
is called. Did you call xmlParseFile() from your application layer or
did you modify the SAX back-end ?

  My implementation of startDocument() SAX callback expect
to get a valid xmlParserCtxtPtr as the userData data block provided
for the callback, i.e. ctxt->userData == ctxt. This should be the case if
you called the standard API.
  If you decided to use the SAX API instead then, you must provide
your own set of callbacks (or if reusing the ones from SAX.c you must
fullfill the assumption I made that the user data block is the current
xmlParserCtxtPtr block).
