[Boost-users] program_options application crashes when printing options descriptions

At some point many of my applications that use the boost.program_options 
libraries started crashing when they attempt to print the options 
descriptions
i.e.
cout << opt_desc;

I believe the problem started when we upgraded to boost 1.33.1 from 
1.32.0 and were using MSVC 7.1.
I'm not trying to figure out the problem using boost 1.33.1 using MSVC 8.0.

Here is the deal if I run the debug version of one of my apps with the 
standard --help option it runs fine. If I run the release version part 
of the help message is displayed but then the application crashes

If I attempt to debug the problem by launching the debug version of 
application from the MS debugger I get a debug assertion failed in 
xstring in a _SCL_SECURE_VALIDATE_RANGE check on operator += (basically 
the new secure checked iterators MS had introduced are complaining about 
  an out of range iterator). Looking at the call stack the problem 
stemmed from line 361 of options_description.cpp (the format_paragraph 
function).

Basically it looks like the program_options library is running afoul of 
the new checked iterators in MSVC 8.0 but since I do know we experienced 
  a problem in using MSVC7.1 I think the problem is more insidious than 
a boundary condition check is overstepping an iterator range.

Has anybody else experienced this type of problem or have any idea's on 
how to fix it?

Thanks

FYI here is the start of my main including my add_options, store, and 
notify calls and the call to display the help message.

o::options_description options_desc("Options");
po::variables_map vm;
int _tmain(int argc, TCHAR* argv[])
{
        int nRetCode = 0;

        // initialize MFC and print and error on failure
        if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
        {
                // TODO: change error code to suit your needs
                _tprintf(_T("Fatal Error: MFC initialization failed\n"));
                nRetCode = 1;
        }
        else
        {
//Setup our program options.
                options_desc.add_options()
                                ("help,h", "Produce help message")

characterization." )

//				("blocks,b", "Produce synchronization blocks")
                        ;

                po::store( parse_command_line(argc, argv, options_desc), vm );
                po::notify(vm);

                if( vm.count("help") )
                {
                        cout << options_desc << "\n";
                        return 1;
                }
