Laziness invites efficiency. I strongly disagree with your point of view: "it is never a compiler error" not only precludes suspicion of the lower levels—voicing your suspicion of problems in lower layers will generally result in ridicule!—but it reducing critical thinking, bars people from looking into "complicated" projects, and makes them overall less efficient and skilled developers. I also disagree that encouraging a bit of wasted time is a problem. What is a few hours, or even days "wasted" learning your lesson once and for all if it greatly improves your debugging skill and efficiency? You do not learn without mistakes. "It is never a compiler error" is a detrimental mindset to have, in that it suggests a mentality where you shut your eyes for anything you did not author. After all, it is too complex, too well-tested, too well-designed, and implemented by much smarter people than you. Compiler, library, application, hardware, train, bridge, it doesn't matter. Not only does this mean that you often won't find the bug you hit, as you won't start instrumenting the faulty LargePopularLibrary—after all, it obviously can't be to blame—but it also means that you won't as much as read library|compiler|kernel|etc source code, much less do development on it, as you think it is above you, despite it by no means being some magical black art. "It could be a compiler error" invites you to consider all possibilities. Immediately blaming the compiler without reasonable evidence would, despite such a mantra, be a result of terrible debugging skills. These debugging skills should be improved through other means than intentionally teaching falsehoods, and if the subject is not an entirely lost cause, it should correct itself in much more valuable ways if a little time is "wasted" on improper debugging. Teach proper debugging techniques instead of lying to others, or yourself.
