--- Comment #5 from Alexander Cherepanov <ch3root at openwall dot com> ---
Not sure this is relevant to static/automatic distinction mentioned above but
the following code uses a static struct, is accepted by gcc and exposes the
problem:

----------------------------------------------------------------------
#include <stdio.h>

static struct s {
  struct sub {
    int x, y;
  } sub;
} s = (struct s){ (struct sub){1, 2}, .sub.y = 3 };

int main()
{
  printf("%d %d\n", s.sub.x, s.sub.y);
}
