Memory leak when using the DOMParser

           Summary: Memory leak when using the DOMParser
           Product: Xerces-C++
           Version: 1.5.1
          Platform: Alpha
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Validating Parser (DTD)
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: Oberson@nagra.com
                CC: Oberson@nagra.com


Hello,
We found a memory leak in Xerces 1.5.1 (and also in Xerces v1.4) C++ when using 
the DOMParser. The leak occurs both when we specify an input file or when we 
use a membug as input source to the parsing method.

The XML file passed as parameter to the method "parse" contains a
DOCTYPE instruction refering to a valid DTD. The DTD itself includes another
valid DTD. All XML files and DTD files are located in the working directory.

We tried to use both Xerces v1.4.0 and xerces v1.5.1 and both versions have the 
problem. However, Xerces v1.5.1 does not leak if the argument setDoValidation 
is set to 0.

Looking at the bug report archive, it seems that this problem has already been 
reported to you. Is it fixed now, and, if yes, when do you plan to release a 
version of Xerces with the fix in? Thanks in advance for your help. Best regards

P.S.: below is a sample program that reproduces the leak.

=============================================
Sample program
=============================================
 
#include <iostream.h>
#include <framework/MemBufInputSource.hpp>
#include <util/PlatformUtils.hpp>
#include <parsers/DOMParser.hpp>
 
main( ) {
 
  int step=0;
  const char* fileName = "test.xml";
 
  cout << "Initialize platform" << endl;
 
  XMLPlatformUtils::Initialize();
  while( 1 ) {
    DOMParser parser;
    parser.setDoValidation( 1 );
    parser.parse( fileName );
    if( step++ %100 == 0 ) {
      cout << step << endl;
    }
  }
}
