--- Comment #4 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
ICEs with -O3:

enum { LUMA_12x16 };
typedef int (*pixelcmp_t)(const unsigned char *, long, const unsigned char *,
                          long);
struct A {
  struct {
    pixelcmp_t sad;
  } pu[];
};
template <int lx, int>
int sad(const unsigned char *p1, long p2, const unsigned char *, long) {
  int a;
  for (int y; y; y++) {
    for (int x = 0; x < lx; x++)
      a += p1[x];
    p1 += p2;
  }
  return a;
}
void setupPixelPrimitives_c(A &p1) { p1.pu[LUMA_12x16].sad = sad<12, 16>; }
