(In reply to jim from comment #5)

Here's a simpler test case that illustrates the same bug (GCC 7.1.0, x86-64,
compiled via "gcc -O2 -S -fsanitize=address v2.i"):

  typedef struct Lisp_Object { long i; } Lisp_Object;
  struct Lisp_String { char *data; };

  Lisp_Object
  server_accept_connection (int sa_family)
  {
    switch (sa_family)
      {
      default:;
        Lisp_Object x = (Lisp_Object) { (long) &(struct Lisp_String) {">"} + 4
};
        return x;
      }
  }
