--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

In GCC 7, GCC didn't crash (with -std=3Dc++17 -fconcepts) but gave a wrong =
error
message:
<source>:11:24: error: no match for call to '(A<false>) (int)'
    int j =3D A<false>{}(0); // Crash
                        ^
<source>:11:24: note: candidate: int (*)(int) <conversion>
<source>:11:24: note:   candidate expects 1 argument, 2 provided

The crash started in GCC 8.=
