Actually, it is the same issue:

    $ cygcheck -s | grep -e binutils -e gcc
    mingw64-x86_64-binutils                 2.25.0.1.23f238d-1     OK
    mingw64-x86_64-gcc-core                 6.3.0-1                OK
    mingw64-x86_64-gcc-g++                  6.3.0-1                OK

    $ cat z.cpp
    #include <iostream>
    main() {
      std::cout << "cout test\n";
    }

    $ x86_64-w64-mingw32-g++ -static -o z z.cpp
    $ ./z
    cout test

So, with both your post and my post, the issue is fixed by not using:

- binutils 2.28.1
- mingw64-x86_64-binutils 2.28.1
- mingw64-i686-binutils 2.28.1

which leaves the last working version:

- binutils 2.25.0
- mingw64-x86_64-binutils 2.25.0
- mingw64-i686-binutils 2.25.0
