Surely it's not a bug every time (but maybe was often enough a bug in the Chromium project, that is several millions lines of code). But in articles about PVS-Studio, and elsewhere, I have seen several cases where code like x+b?y:0 was a bug in good and real code. But I don't yet know how common those problems are. I will study some more on this.

Good.

There is also the problem of code like this, that will require one or more solutions for D2. Defining or refusing or this kind of code are the possibilities (or both of such solutions, in different situations):
x = x++;

Thank you for your answers,
