--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started to be rejected with r239268.
If it is a bug, it is therefore a regression.
clang++ doesn't seem to reject it, and even before the above revisions we'd
reject vars without initializers in constexpr functions if they weren't empty.
