             Bug #: 55043

           Summary: issue with nesting unordered_map containing unique_ptr

                    into vector

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: libstdc++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: boris.big...@hotmail.com





The program below does not compile using gcc-4.7.2 or clang-3.1 together with

libstdc++-4.7.2. Using gcc-4.6.3 with corresponding libstdc++ or clang-3.1 with

clangs libc++ works. Nesting uim in other containers like pair, tuple, or

unordered_map works too. Apparently, only vector is affected.



#include <memory>

#include <unordered_map>

#include <vector>



int main() {

    typedef std::unique_ptr<int> uip;

    typedef std::unordered_map<int, uip> uim;

    typedef std::vector<uim> uiv;

    uiv v;

    v.emplace_back(uim());

}
