[Vtd-xml-users] Memory Leaks [SEC=UNCLASSIFIED]

Hi Jimmy,

I bit the bullet and converted my software to use your C++ library (32 bit). I was using an old version of your C library with my own C++ wrapper.

It all seems to work OK.

However Visual Leak Detector reports a large number of 64 byte memory leaks.

I am including a code fragment in case I am doing something wrong.

bool CPropertyDocument::hasProperty(const std::string &propName)
{
    unsigned short wcstr[200];
    size_t len;
    mbstowcs_s(&len, (wchar_t *)wcstr, 200, propName.c_str(), propName.size());
    wcstr[len] = 0;
    wchar_t qry[200];
    wcscpy_s((wchar_t *)qry,200,L"//property[@id='");
    wcsncat_s((wchar_t *)qry,200,(wchar_t *)wcstr,len);
    wcscat_s((wchar_t *)qry,200,L"']");
    ap->selectXPath(qry);
    int result = ap->evalXPath();
    ap->resetXPath();
    if (result == -1)
    {
        return false;
    }
    return true;
}

Output from VLD

---------- Block 3980 at 0x001C0610: 64 bytes ----------
  Call Stack:
    c:\thirdpartylibs\cpp\ximpleware-2.12-c++\vtd-xml\xpathparser.yy (302): yy::xpathParser::parse
    c:\thirdpartylibs\cpp\ximpleware-2.12-c++\vtd-xml\xpath_driver.cc (60): xpath_driver::parse
    c:\thirdpartylibs\cpp\ximpleware-2.12-c++\vtd-xml\autopilot.cpp (525): com_ximpleware::AutoPilot::selectXPath
    c:\myprojects\msvc\hil\subsystem\rtobject\propertydocument.cpp (182): CPropertyDocument::hasProperty

I get similar for all calls to selectXPath.

Am I doing something wrong?

Cheers
Russell
