Well, if that's truly what you believe, then okay, but I disagree that C is perfect as it is, and I certainly disagree that we should forget about overflow. > He said: > > He's saying that an overflow check on every single operation is simply > not necessary if the programmer exercises due care to add his own checks > in circumstances where an overflow might occur. You are conflating two of his points. He's actually saying that in /some/ cases an overflow check is redundant, and he's right. I gave an example of such code. > Now we have the solution: it is up to the programmer of course. That's one solution. Another solution is for the implementation to add a runtime check, and this is what you are proposing. My own view is that such a check would be a good thing /provided/ it is controllable by the programmer in some way --- either through a command line switch (for code that is not able, for portability reasons, to use extensions) or, for code that does have that freedom, perhaps a pragma: #pragma LCC_WIN OC_Enable and #pragma LCC_WIN OC_Disable (or whatever your pragma naming convention might be). > We discussed here the same thing six and half years ago because a first > discussion I started on Sep 1, 2009.
