Is std::ofstream movable?

Question

I have this map which compiles fine in MSVC10 :

std::map m_logFiles;

But on ubuntu using g++ 4.5 with C++

Answer 1

I asked a similar question earlier, and later found that GCC doesn't seem to support movable fstreams yet (I just tested GCC 4.6.1) as detailed in this answer.

Answer 2

std::ofstream is movable. This program compiles for me using clang/libc++:

#include <string>
#include <fstream>
#include <map>

int main()
{
    std::map<std::string, std::ofstream> m_logFiles;
}

Reference 27.9.1.11 [ofstream.cons].
