6690,access violation using global path object,Claudio Bley,Beman Dawes,"I think this is an instance of ""static initialization order fiasco"".

The following code crashes with ""Access violation reading location 0x00000000"".
{{{
#!cpp
#include <boost/filesystem.hpp>
#include <iostream>

const boost::filesystem::path p(""test"");

int main(int argc, char *argv[])
{
  std::cout << p << std::endl;
}
}}}
This is caused by ```codecvt_facet``` not being initialised on its first use. Call Stack:
