Re: [boost] [asio] question on boost::asio::ssl::stream::async_shutdown expected behaviour

Dear all,

first of all, kindly please let me know if I'm sending messages in the wrong
place.

I've investigated more in-deep this issue and it seems that async_shutdown
is producing a stack overflow.
This has been tested with latest boost version.
The result is the same if I try with Windows Xp (MSVC v8.0-express) and with
a Linux RHEL 4 64bit.
I've enclosed the linux coredump.

Please let me know and thanks in advance.

Kind regards,

Carlo Medas
