--- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> ---
This changed in r15-3721-ga2746e4347076e to implement
https://eel.is/c++draft/dcl.fct.def.default#2.6

But since the constructor is explicitly defaulted *after* its first
declaration, that bullet does not apply and the program is still ill-formed.
