--- Comment #5 from Mateusz Zych <mte.zych at gmail dot com> --- Hello Jakub! You're right! I haven't realized that the issue was with the P2747R2. Agreed - since the operator placement delete "intentionally performs no action", marking it constexpr should be non-controversial. Thank you for submitting the LWG4477 issue and committing the required change into GCC's libstdc++. Hopefully your proposed resolution will be accepted into C++26. Lastly, I confirm that your change works. I tested the GCC trunk by compiling a code which throws an exception during invocation of the std::vector<T, Alloc>::emplace_back(). Thank you, Mateusz Zych
