Slightly more reduced testcase:

void
foo (int *x, int *y)
{
  int i;
  for (i = 0; i < 11; i++)
    y[i] = (x[i] == 1) ? i + 1 : -(i + 1);
}

The following:

void
bar (int *x, int *y)
{
  int i;
  for (i = 0; i < 64; i++)
    y[i] = (x[i] == 1) ? i + 1 : -(i + 1);
}

ICEs with
internal compiler error: in get_initial_def_for_induction, at
tree-vect-loop.c:2659
instead.
