Hi,
Apologize if this is not the right place for this mail.

This program (it has been narrowed down from a larger program) always
crashes after compiled in vs2008 Release(Win32) mode under windows 7. I am
not familiar with assembly code and don't know it's a bug of compiler or
boost::ends_with or boost::asio::buffers_iterator. It can be compiled and
executed with g++ in Ubuntu without any problem.

People said it's very unlikely to be compiler's bug, but when compiled in
debug moded(or disable optimization), the problem does disappear.

I have been stuck with this problem for quite a few hours. Any help is
appreciated. Thanks in advance.

#include <iostream>#include <string>#include <boost/asio.hpp>#include
<boost/algorithm/string.hpp>
typedef boost::asio::buffers_iterator<boost::asio::const_buffers_1>
iterator_t;typedef boost::iterator_range<iterator_t> range_t;static
const std::string LINE_END_MARK = "\r\n";
int main(int argc, char* argv[]){
    boost::asio::streambuf _buf;
    std::ostream os(&_buf);
    os<<"END\r\n";

    iterator_t cursor = boost::asio::buffers_begin(_buf.data());
    iterator_t end = boost::asio::buffers_end(_buf.data());

    std::ostream_iterator<char> it(std::cout," ");
    std::copy(LINE_END_MARK.begin(), LINE_END_MARK.end(), it);

    range_t r(cursor, end);
    if(!boost::ends_with(r, LINE_END_MARK))
        return 0;
    return 1;}
