At Gamefest in July I gave a talk entitled "Here Be Dragons: C++ Undefined Behavior." As expected, the presentation drew many raised eyebrows and some strong reactions, which was exactly the point. Undefined behavior in C++ is bad news, and should be avoided at all costs. However, it’s surprising how many instances of undefined behavior can crop up in average C++ code. You can download the PowerPoint presentation and the audio transcript here, and listen to it at your leisure.
In fact, you can download most of the presentations given at Gamefest this year. The full list is available at http://xnagamefest.com/presentations.htm. Enjoy!
