--- Comment #3 from Tom de Vries <vries at gcc dot gnu.org> ---
Further reduced example (at -O2 -floop-interchange):

enum enums { PLANE_TYPES };

struct RD_COUNTS
{
  enum enums coef_counts[2][2];
};

struct A
{
  struct RD_COUNTS rd_counts;
};

int j;

struct A *fn1_td;

void
fn1 (void)
{
  int i;

  for (i = 0; i < 2; i++)
    for (j = 0; j < 2; j++)
      fn1_td->rd_counts.coef_counts[i][j] = PLANE_TYPES;
}
