F200 Hands Samples can't work

[荣威_赖_]

when I run the Hands Samples(Hands 3D View,Hands Viewer and Hands Console),the programe break at

void __cdecl _free_base (void * pBlock)
{

        int retval = 0;


        if (pBlock == NULL)
            return;

        RTCCALLBACK(_RTC_Free_hook, (pBlock, 0));

        retval = HeapFree(_crtheap, 0, pBlock);
        if (retval == 0)
        {
            errno = _get_errno_from_oserr(GetLastError());
        }
}

at line

retval = HeapFree(_crtheap, 0, pBlock);

I don't know what's wrong.Anyone help?Thanks for any help.
