--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started to ICE with r247048.
This got fixed or made latent with r266956 on the trunk.
Slightly cleaned up testcase:
int a, b, d;
unsigned c;
float e, f, g;
void
foo (void)
{
  float *i = &g;
  for (; c < 10; c += 3)
    for (; d; d += 3)
      {
        a = *i;
        g = f + 0;
        f = b + *i + (b - e + 305219) + -b + 3;
      }
}
