------- Comment #3 from rguenth at gcc dot gnu dot org  2008-08-01 11:15 -------
Confirmed.  Reduced testcase:

typedef float v4sf __attribute__ ((vector_size(16)));
typedef v4sf v4;
typedef union {
  v4sf v[4][4];
} m4v4;
void skew3(const v4 _v, m4v4 *dV2_dv)
{
  float *v = ((float *) &_v);
  if (dV2_dv)
    dV2_dv->v[1][0] = dV2_dv->v[0][1] = (v4){ v[1], v[0], 0., 0};
}
