Re: [Boost-users] [asio] reported memory leaks when using MFC

Hi Christopher, attached to this email is a server and a client
program. They are console program but they are using MFC's new
operator. It's assumed that boost is in c:\boost and the libs are in
c:\boost\stage\lib . If that is not correct on your machine you need
to change some settings.

It's OK to run them just a few seconds. MFC will report quite a few
memory leaks. Also Purify is reporting the leaks.

Let me know when you are having any issues.

Thanks,
Christian
