13135,boost::filesystem::exists silently fails to work on MSVC with newly created symlink,Antony Polukhin,Beman Dawes,"The following program:
{{{
#include <boost/filesystem/operations.hpp>
#include <cassert>
#include <fstream>
#include <iostream>

int main() {
    boost::system::error_code error;

    boost::filesystem::create_directories(""dir/subdir"", error);
    assert(!error);

    std::ofstream ofs(""dir/subdir/file.txt"");
    ofs << ""Boost.Filesystem is fun!"";
    assert(ofs);
    ofs.close();

    boost::filesystem::create_symlink(""dir/subdir/file.txt"", ""symlink"", error);
    if (!error) {
        std::cerr << ""Symlink created\n"";
        assert(boost::filesystem::exists(""symlink""));
    } else {
        std::cerr << ""Failed to create a symlink\n"";

        boost::filesystem::remove_all(""dir"", error);
        assert(!error);

        boost::filesystem::remove(""symlink"", error);
        assert(!error);
    } /*if (!error)*/
} /*main*/

}}}

Works well on Linux and Windows+MinGW but fails to work on msvc-14.0:
{{{
--- Stderr:
Symlink created
Assertion failed: boost::filesystem::exists(""symlink""), file .\main.cpp, line 20
--- Ret code: 3

}}}

Failed run can be found here: https://ci.appveyor.com/project/apolukhin/boost-cookbook/branch/second_edition/job/1ycwqk36phd8h8il

P.S.: Code from above worked well a few months ago. Looks like some recent change broke the example.",Bugs,new,To Be Determined,filesystem,Boost 1.65.0,Problem,,exists fs filesystem msvc,
