[Boost-users] Portable stack trace mechanism?

I've written this code several times and thought boost might have something. No, it doesn't, but I found this old bit thread: http://lists.boost.org/Archives/boost/2010/10/172303.php

From the evidence I can conclude that it never made it in, but the thread gives no indication as to why. I don't want to resurrect something that's already been fully hashed and excluded, but if it never made it in simply because nobody carried the torch forward, perhaps I could be the new bearer.
