--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fails in GIMPLE verification because
vect_cst__127 = {_172, _162};
references the released SSA name _172 after BB vectorization.
Not a dup of PR66856.
It looks like we end up building a SLP node from scalars that are pattern
stmts. Oops.
