I will continue to consider code which That strikes me as a poor assumption. Just like anyone else, C++ implementors often find themselves forced to consider other issues to be more important than quality. Some of them don't even need any forcing. > can only be generated when there is known undefined behavior to be > nonsense. The standard allows it, but reality forbids it. Reality forbids very little; far less than you're likely to be able to reliably predict. If you consistently write code that allows undefined behavior, because you "know" it couldn't possibly be "sanely" mishandled, I guarantee you'll run into trouble you could have avoided, and I expect it won't take long. When you run into that trouble, there's a good chance the implementor will be able to you a sane explanation that you hadn't even considered. [ comp.std.c++ is moderated.
