[Bug tree-optimization/24059] New: [4.1 Regression] ICE with -ftree-vectorize -O2

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I was trying -O2 -g -ftree-vectorize while bootstrapping and ran into this.
Reduced testcase:
struct pred_data {
  unsigned char codes[((int) 100)];
};
void compute_predicate_codes (char *codes, struct pred_data *p)
{
  int i;
  for (i = 0;i < ((int) 100);i++)
    codes[i] = p->codes[i] ? 2 : 0;
}

----------
This does not happen with -m32.
