            Bug ID: 32642
           Summary: string::insert and append no longer work with
                    move_iterator
           Product: libc++
           Version: 4.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

Test code:

#include <string>

template <typename Collection>
void insert(Collection& dest, Collection src, size_t pos)
{
    dest.insert(std::next(dest.begin(), pos),
std::make_move_iterator(src.begin()), std::make_move_iterator(src.end()));
}

int main()
{
    std::string s1, s2;
    insert(s1, std::move(s2), 0);
}

The command line and the result:

~/tmp$ clang++-4.0 test.cpp -std=c++11 -stdlib=libc++ -o test
