--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
Indeed, in ensure_literal_type_for_constexpr_object we check:
      if (CLASS_TYPE_P (type) && !COMPLETE_TYPE_P (complete_type (type)))
before calling literal_type_p but that doesn't cover the case of an array of
incomplete element type.

(because the compiler was built with optimizations, the stack trace is missing
a second literal_type_p call (semantics.c:7369))
