It's interesting since the cost model needs to be disabled to reproduce it.

It looks like when it is one of the load nodes already has a VEC_STMT so the
assert crashed in schedule_slp_node

  vec_stmts = {
    m_vec = 0x4e0e870
  },

>>> dbgrep (node)
# VUSE <.MEM_6(D)>
_14 = REALPART_EXPR <*tfn_7(D)>;

If that helps.
