[xml] [xmlParser] xmlFreeDoc do not free memory allocated with xmlParseFile

Hi,

Again... :-)

Using "xmlFreeDoc ()" on a "xmlDocPtr" initialized with "xmlParseFile
()" do not free anything.

Here is the output of a basic program that just initialize "doc" and
free it just after:

----------
grinch badiou:~$ cat test.c
#include <libxml/parser.h>

void main (void)
{
  xmlDocPtr doc = NULL;

  printf (">> Before parsing:\n----------\n");
  system ("free -m -o");
  printf ("----------\n");

  doc = xmlParseFile ("/home/grinch/test.xml");

  printf (">> After parsing:\n----------\n");
  system ("free -m -o");
  printf ("----------\n");

  xmlFreeDoc (doc), doc = NULL;

  printf (">> After freeing:\n----------\n");
  system ("free -m -o");
  printf ("----------\n");
}
grinch badiou:~$ ./test

-> 281M used before, 500M after parsing doc, and 500M after freeing doc.

Do I need to do anything else to free it?

Thanks,
