--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
It used to compile, then since r269003 I see

96241.C:19:3: error: accessing value of ‘‘result_decl’ not supported by
dump_expr<expression error>’ through a ‘s’ glvalue in a constant expression
   19 | }();
      |   ^

and since r10-6437-g0712ea6313bc44f9ae8feb235c1b02c92cdd0527

internal compiler error: in verify_ctor_sanity, at cp/constexpr.c:3987
   19 | }();
