          Assignee: unassigned at gcc dot gnu.org
          Reporter: carlo at gcc dot gnu.org
  Target Milestone: ---

g++ 7.0.1 fails on

    #include <vector>
    struct B { B(B&&) = delete; };
    std::vector<B> v;
    int main() { v.reserve(8); }

error: use of deleted function 'B::B(B&&)'

while clang 5.0.0 compiles it.=
