I thought it might be because we found a way to use memcpy instead, which would
have been good, but no, the vect dump shows an extremely common gcc issue

missed:  not vectorized: more than one data ref in stmt: MEM[(struct
_Tuple_impl *)__cur_14].D.36092 = MEM[(struct _Tuple_impl
&)__first_19].D.36092;
