   TLDR: For almost 1/6 of a century, the C++ standards broke the simplest infinite loop and only just recently fixed it.

   Idiots!

   Don’t they really that people write real programs to solve real problems? This isn’t a theoretical academic exercise!

      > the simplest infinite loop

      An infinite loop which does nothing is practically useless. So, compilers optimize it out. That's the whole philosophy of modern compilers - to reduce execution time by preserving semantics. In case of an infinite loop elimination it's an optimization making code infinite times faster.

         But also very different. If code below this loop executes after elimination and wouldnt have before, that is a very significant change in semantics
