Crash in boost::asio::basic_streambuf

[luliu@…]

Hi All,

Our program crashed in boost::asio::streambuf while streambuf was reserving more spaces.

The related codes using boost::asio::streambuf is like this:

boost::asio::streambuf send_buffer; 

std::ostream send_stream(&send_buffer);
send_stream << "MESSAGE...";
send_stream << flush();

...
boost::asio::async_write(ssl_stream, send_buffer, ...);

The crash happened when boost::asio::streambuf were reserving more space after streambuf exceeded 512 bytes.

Here is the crash stack.
