--- Comment #14 from mm-nospam at outlook dot co.nz ---
The bug still occurs for the same test case with the f() function modified =
as
such:

    X f()
    {
      try {
         X x(true);
         return X(false);
      } catch(...) { }

      return X(false);
    }

The first X(false) is constructed and never destructed.

This example also occurs in [except.ctor]/2 of the C++17 standard, note that
since C++17 X's destructor should be marked as noexcept(false) in the test
case.=
