[snip code]

I made the changes you requested and unfortunately things aren't any
clearer.  What I'm seeing now is error_code == SSL_ERROR_SYSCALL.  However,
the line I added above:

    int sys_error_code = asio::detail::socket_ops::get_error();

sys_error_code == 0

Therefore, when the error happens, this return gets called

          if (error_code == SSL_ERROR_SYSCALL)
            return handler_(asio::error(sys_error_code), rc);

Which boils down to:
          if (5 == SSL_ERROR_SYSCALL)
            return handler_(asio::error(0), -1);

Since sys_error_code is zero, I no longer get an asio::error in my handler
and my code continues to try to read from the socket, which causes lockups
and assertion errors in my code.

I think I preferred the old way :).  Are there any other changes you would
like me to try?

Thanks,
Scott
