--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> ---
With the hack and PR101293 fixed we're still left with

Memory reference 13: *d_28(D).lam1.v
Memory reference 14: VIEW_CONVERT_EXPR<vector(32) unsigned char>(*d_28(D).l=
am1)

because the access types are incompatible (v4df vs v32qi).  Possible to hack
around but the initial hack creating the V_C_E has issues enough (though
handling the aggregate copy in LIM will inevitably run into incomaptible
types compared to other refs as well).

How I love the fun of C++ and all the abstraction when using it ... :/=
