Serialization of stl container with non-copyable value

[mohsen.tamiz@…]

A stl container which stores a non-copyable value can not be serialized and gives a compile error about copy constructor. I used g++-4.18 with c++11 flag on. I attached my code to this bug, it is a minimal code which reproduces the error.

minimal code which reproduces the error

Using g++-5.x can compile the program when container is std::vector bu another containers like std::unordered_map causes the same compile error even with g++-5.x. I have created a ​question in stackverflow about this bug.

By changing line 43 of archive_input_unordered_map.hpp from:

s.insert(t.reference());

to :

 s.emplace(piecewise_construct,
           forward_as_tuple(std::move(t.reference().first)),
           forward_as_tuple(std::move(t.reference().second)));

The error disappear, and it works.

fixed in 1.61 also fixed for archive_input_unordered_set
