--- Comment #1 from Dhruv Chawla <dhruvc at gcc dot gnu.org> ---
Forgot to post the ICE itself (from compiler explorer):

during GIMPLE pass: vect
<source>: In function 'f':
<source>:6:1: internal compiler error: in vectorizable_lane_reducing, at
tree-vect-loop.cc:6861
    6 | f (void)
      | ^

Either caller fails, in the case of SPEC the error occurs in
vect_create_constant_vectors.
