["dalej at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following gets an ICE with -O3 -ftree-loop-linear:

int x[6][5][4];
int y[6][5][4];
void initx(void)
{
  int a,b,c;
  int index = 0;
  for(a = 5; a >=2; a--)
    for (b = (a - 1); b >=1; b--)
      for (c = (b - 1); c >=0; c--)
        x[a][b][c] = index++;
}
void inity(void)
{
  int d,e,f;
  int index = 0;
  for(d = 5; d >=2; d--)
    for (e = (d - 1); e >=1; e--)
      for (f = (e - 1); f >=0; f--)
        y[d][e][f] = index++;
}
void foo() {
  initx();
  inity();
}
