------- Comment #5 from rguenth at gcc dot gnu dot org  2008-12-03 16:38 -------
Still warns for

truct xxx {
    short a;
    short b;
    void *c;
};

void bar(struct xxx);

void foo(struct xxx *p, int i)
{
  struct xxx s0 = *p;
  struct xxx s = s0;
  if (s.a) i++;
  bar(s);
}

at -O -m32 -Wuninitialized.
