--- Comment #7 from Marc Glisse <glisse at gcc dot gnu.org> ---
Hmm, with the static_cast, the front-end produces:
<<cleanup_point return <retval> = (struct string_view &) (struct string_view *)
NON_LVALUE_EXPR <(struct string_view &) &(n != 0 ?
std::experimental::fundamentals_v1::basic_string_view<char>::remove_prefix
((struct string_view *) s, n);, *s; : *s)>>>;
while without it, I get:
<<cleanup_point return <retval> = (struct string_view &) (n != 0 ?
std::experimental::fundamentals_v1::basic_string_view<char>::remove_prefix
((struct string_view *) s, n);, (struct string_view *) s; : (struct string_view
*) s)>>;
I also find it fishy.
(note that you need -O2 or more for the warning)
