Bug on XercesC 1.5.2 ???

[Jorge Pozo Ramirez <j....@externo.mju.es>]

    Hi there.

     I'm having troubles with Xerces and multiple file parsing. I'm working
on SCO OpenServer, with 1_5_2 version of XercesC.

    On the same program, I DomParse a XML file. I keep the Document in a
DOM_Document object, and then I delete the parser. Then I create a new
DomParser and repeat it three times.

    Everything goes OK, but when the program ends, and destructors are
working, I receive a Memory Fault from
XMLPlatformUtils::atomicDecrement ()

This is the call stack:

(gdb) bt

#9  0x804d949 in main (argC=6, argV=0x8047ca8) at almacena.cpp:961
#10 0x804c6eb in _start ()

The pseudocode of my app is as follows:

main{
  Xerces::Initialize;
  DOMParser parser = new DOMParser;
  DOMDocument doc1;
  DOMDocument doc2;
  DOMDocument doc3;
  [...]
  parser->parse(file1);
  doc1 = parser->getDocument();
  delete parser;
  parser = new DOMParser;
  parser->parse(file2);
  doc2 = parser->getDocument();
  delete parser;
  parser = new DOMParser;
  parser->parse(file3);
  doc3 = parser->getDocument();
  delete parser;
[...]
  printDoc1;  // Almost same code as DOMPrint
  printDoc2;  // Almost same code as DOMPrint
  printDoc3;  // Almost same code as DOMPrint
[...]
  Xerces::Terminate;
}

Is there something I'm doing wrong?. Thank you.

Jorge
