gcc-bugs at marehr dot dialup.fu-berlin.de changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|std::vector | |std::vector | |std::views::drop_while | |std::views::drop_while, |std::views::reverse, cbegin |cbegin does not work |does not work | --- Comment #1 from gcc-bugs at marehr dot dialup.fu-berlin.de --- Sorry, we have a view which is similar to `std::views::drop_while` where I could just replace the name and it gave me the same error, but using `std::views::drop_while` gives me the error already without the reverse. So I changed the ticket. ```c++ #include <ranges> #include <vector> int main() { std::vector<int> text1{}; auto drop_none = [](auto const &) constexpr { return false; }; auto accept_any = [](auto const &) constexpr { return true; }; auto && view1 = text1 | std::views::reverse; auto && view2 = text1 | std::views::drop_while(drop_none); auto && view3 = text1 | std::views::take_while(accept_any); auto && view4 = text1 | std::views::filter(accept_any); std::ranges::cbegin(view1); std::ranges::cbegin(view2); // does not work std::ranges::cbegin(view3); std::ranges::cbegin(view4); // does not work } ``` (https://godbolt.org/z/E97_Tq)
