This is one where I suspect we don't disagree. But "all the time" can have a very different feel between people. It also used to happen that just changing processors was likely to find some problems in the code. I have no doubt that still happens, but I'd also expect it has reduced. Some of this has to be a convergence on far fewer compilers than we used to encounter. I know there are still many c compilers. Seems there are only two common ones, though. Embedded, of course, is a whole other bag of worms.
