10194,basic_xml_grammar<wchar_t> parses class_id failed,Andrew Xu <xulei.js@…>,Robert Ramey,"I found this issue when I used xml wserialization to save config in polymorphic case. After debugging, I found basic_xml_grammar<wchar_t> failed to parse ""class_id"" under some conditions. There are some info for this issue:
1. Compile with NDEBUG, without NDEBUG no this issue.
2. basic_xml_grammar<char> works fine.
3. Compile with GCC (when compile with VS2010, no this issue)
Detail of GCC:
gcc -v

I trimmed the test code:

#include <boost/archive/impl/basic_xml_grammar.hpp>
#include <fstream>
#include <iostream>

using namespace boost::archive;


int main()
{
    std::wifstream ifs(""./dashboard.xml"");

    if (ifs) {
        basic_xml_grammar<wchar_t> xmlGrammer;
        xmlGrammer.parse_start_tag(ifs);

        std::wcout << ""rv.class_id="" << xmlGrammer.rv.class_id << std::endl;
    }
    else {
        std::cout << ""File doesn't exist."" << std::endl;
    }

    return 0;
}

and the dashboard.xml is very simple with only one line:
