--- Comment #3 from Jason Liam <jlame646 at gmail dot com> --- (In reply to Jakub Jelinek from comment #1) > This is rejected with -std=c++20 since > r11-532-g4b38d56dbac6742b038551a36ec80200313123a1 > and the commit log states that it is intentional to apply it only for C++20 > mode because the DR wasn't against C++17. > So why do you think otherwise? > https://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#2237 > also states: > (Note that this resolution is a change for C++20, NOT a defect report > against C++17 and earlier versions.) Additionally note that i'm already aware of the cwg defect link that you provided because i once used it here: https://stackoverflow.com/questions/71972000/is-having-a-declaration-stackt-for-the-default-ctor-valid-inside-a-class-te/71981884#71981884 But that cwg defect does not apply here. This is a different gcc bug.
