--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
I encountered a similar problem when testing views::join_with:
#include <string>
#include <ranges>
constexpr std::string_view rs[] = {"42"};
static_assert(!std::ranges::empty(rs |
std::views::join_with(std::string(""))));
error: accessing ‘std::__cxx11::basic_string<char>::<unnamed
union>::_M_allocated_capacity’ member instead of initialized
‘std::__cxx11::basic_string<char>::<unnamed union>::_M_local_buf’ member in
constant expression
