Bug ID: 59434 Summary: move_iterator is broken for input iterators with an rvalue as reference type Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: major Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: cheparukhin at yandex dot ru move_iterator<Iterator> is correct only for iterators which satisfy forward iterator requirements in the part that requires Iterator::reference to be the same as Iterator::value_type. If the reference type is an rvalue, i.e. a special proxy object implicitly convertible to value_type (as in vector<bool>), move_iterator::operator* returns a dangling reference to a local variable, which causes a segmentation fault (although this doesn't happen with vector<bool> for some reason, but happens with more complex value_types). This is because move_iterator<Iterator>::operator* returns Iterator::value_type&&. I suggest it should return remove_reference<Iterator::reference>::type&& instead, it seems that in this case the problem should be solved.
