[xml] xmlFree crashing

[phils micronet com au]

HI,
I am using the binaries built at zlatkovic.com.
When I am calling xmlFree after calling xmlNodeListGetString, the program
is crashing with a really weird unhandled exception

Unhandled exception at 0x026332a0 in
dconnect.exe: 0xC000001E:  An attempt was made to execute an invalid
lock sequence.


For structural reasons I am not linking
the DLL into my application by using LoadLibrary and GetProcAddress. I
am pretty sure the problem is that the xmlFree address is incorrect, or
I am passing an invalid argument but I cant see what it could be.


My code is shown below


xmlFreeFunc lpXMLFREE = NULL;

HMODULE hXML = NULL;

BOOL InitXML()
{
        if
(hXML)
             
  return(TRUE);

        hXML = LoadLibrary("libxml2.dll");
        if
(hXML == NULL)
             
  return(FALSE);

        if
(!(lpXMLNEWDOC = (LPXMLNEWDOC) GetProcAddress (hXML, "xmlNewDoc")))
             
  return(FALSE);
        if
(!(lpXMLFREEDOC = (LPXMLFREEDOC) GetProcAddress (hXML, "xmlFreeDoc")))
             
  return(FALSE);
        if
(!(lpXMLNEWNODE = (LPXMLNEWNODE) GetProcAddress (hXML, "xmlNewNode")))
             
  return(FALSE);
        if
(!(lpXMLDOCSETROOTELEMENT = (LPXMLDOCSETROOTELEMENT) GetProcAddress (hXML,
"xmlDocSetRootElement")))
             
  return(FALSE);
        if
(!(lpXMLDOCGETROOTELEMENT = (LPXMLDOCGETROOTELEMENT) GetProcAddress (hXML,
"xmlDocGetRootElement")))
             
  return(FALSE);
        if
(!(lpXMLNEWNS = (LPXMLNEWNS) GetProcAddress (hXML, "xmlNewNs")))
             
  return(FALSE);
        if
(!(lpXMLNEWCHILD = (LPXMLNEWCHILD) GetProcAddress (hXML, "xmlNewChild")))
             
  return(FALSE);
        if
(!(lpXMLNEWTEXTCHILD = (LPXMLNEWTEXTCHILD) GetProcAddress (hXML, "xmlNewTextChild")))
             
  return(FALSE);
        if
(!(lpXMLSAVEFORMATFILEENC = (LPXMLSAVEFORMATFILEENC) GetProcAddress (hXML,
"xmlSaveFormatFileEnc")))
             
  return(FALSE);
        if
(!(lpXMLSAVEFORMATFILE = (LPXMLSAVEFORMATFILE) GetProcAddress (hXML, "xmlSaveFormatFile")))
             
  return(FALSE);
        if
(!(lpXMLPARSEFILE = (LPXMLPARSEFILE) GetProcAddress (hXML, "xmlParseFile")))
             
  return(FALSE);
        if
(!(lpXMLSTRCMP = (LPXMLSTRCMP) GetProcAddress (hXML, "xmlStrcmp")))
             
  return(FALSE);
        if
(!(lpXMLNODELISTGETSTRING = (LPXMLNODELISTGETSTRING)GetProcAddress(hXML,
"xmlNodeListGetString")))
             
  return(FALSE);
        if
(!(lpXMLFREE = (xmlFreeFunc)GetProcAddress(hXML, "xmlFree")))
             
  return(FALSE);
        return(TRUE);
}

void msaxmlFree(void
*v)
{
        lpXMLFREE(v);
}
