        <pre>Consider the following program (prog.cc):

  enum struct E a;
  enum class F b;
  enum G : int c;
  enum struct H : int d;
  enum class I : int e;
  int main() {}

Compile the program with the following command line:

  clang++ prog.cc -std=c++14 -pedantic-errors

No error messages are given. This was not expected since the program is
ill-formed. 

For comparison GCC does not accept the program.

Note that if this was intended as a compiler extension, it doesn't even work
well as such. Try for example to make c, d or e pointers.</pre>
