Bug ID: 106612 Summary: ranges::iter_move does not consider iterator's value categories Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: hewillk at gmail dot com Target Milestone: --- The following case should be a constraint not satisfied rather than a hard error since we cannot dereference the I of an rvalue. #include <ranges> struct I { using difference_type = std::ptrdiff_t; using value_type = int; value_type& operator*() const &; void operator*() && = delete; I& operator++(); I operator++(int); bool operator==(const I&) const; }; int main() { return std::ranges::iter_move(I{}); } https://godbolt.org/z/xP4GWT3qv
