[Bug c/30120] [4.3 Regression] silent miscompilation of argument passing

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2006-12-08 12:46 -------
Confirmed.  Reduced testcase:

static void foo (double a, double weight, const double *ring, double *phase) 
{
  *phase = *ring * weight;
}

void foo2 (void)
{
  foo (0, 1, (double*)0, (double*)0);
}

int main(void)
{
  double t1=1, c1;
  foo(0, 1,&t1,&c1);
  return (c1>0.5) ? 1:0;
}
