--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to jim.gray from comment #3) > The "correct" answer is also provided by the Intel C++ compiler, > so apparently GCC is the odd one out. I think MSVC is the odd one out really. see below. You can also do the testing yourself at https://godbolt.org/ to see that. Huh? Maybe ICC on windows gives a different answer than ICC on Linux. Which might make sense if ICC on Windows is trying to provide bug for bug compatibility with MSVC. ICC gives: icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended compiler moving forward. Please transition to use this compiler. Use '-diag-disable=10441' to disable this message.
