--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC 8+ rejects the first "// accepted" in the reduced testcase.
GCC 9+ rejects both.

Note both are only with C++11 standard (or greater).

Because in C++98 the constant expression which evulates to 0 is considered a
null pointer :).
