------- Comment #4 from jojelino at gmail dot com  2010-09-11 20:59 -------
this causes ICE
confirmed with gcc -O3 -msse2  -std=gnu99
reduced testcase 

typedef unsigned char uint8_t;
typedef struct foo2
{
  int offset[4];
  uint8_t* ref[4];
} foo2;
int
foo(const foo2 *fooval)
{
  uint8_t *source[4] =
    { fooval->ref[0], fooval->ref[1], fooval->ref[2] };
  int strides[4] =
    { fooval->offset[0], fooval->offset[1], fooval->offset[2] };
  for (int i = 0; i < 4; i++)
    {
      strides[i] = -strides[i];
      source[i] -= strides[i];
    }
  return source[0];
}
int
main()
{
  foo2 fool;
  int ret = foo(&fool);
  return ret;
}
