--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
btw, clang rejects this with

t.c:17:33: warning: initializer partially overrides prior initialization of
this subobject [-Winitializer-overrides]
   17 | const struct T t1 = { .s = s, .s.r.b = 5 };
      |                                 ^~~~~~~~
t.c:17:28: note: previous initialization is here
   17 | const struct T t1 = { .s = s, .s.r.b = 5 };
      |                            ^
t.c:17:16: error: cannot compile this static initializer yet
   17 | const struct T t1 = { .s = s, .s.r.b = 5 };
      |                ^
1 warning and 1 error generated.

and we accept even with -std=c99 -pedantic -pedantic-errors
