Yes, and when compilers fail, it's a very complex problem to solve, that usually requires many hours from experienced dev. Luckily, (1) Compilers are reproducible (or at least repeatable), so you can share your problem with other, and they can help. (2) For common languages, there are multiple compilers and multiple optimization options, which (and that's _very important_) produce identically-behaving programs - so you can try compiling same program with different settings, and if they differ, you know compiler is bad. (3) The compilers are very reliable, and bugs when compiler succeeds, but generates invalid code are even rarer - in many years of my career, I've only seen a handful of them. Compare to LLMs, which are non-reproducible, each one is giving a different answer (and that's by design) and finally have huge appear-to-succeed-but-produce-bad-output error rate, with value way more than 1%. If you had a compiler that bad, you'd throw it away in disgust and write in assembly language. |
