Looks like a similar problem to PR32378:
(compute_affine_dependence
(stmt_a =
D.1398_74 = (*aa_73(D))[D.1397_72])
(stmt_b =
(*aa_73(D))[D.1393_68] = D.1408_88)
(subscript_dependence_tester
(analyze_overlapping_iterations
(chrec_a = {D.1396_71 + 1, +, 1}_2)
(chrec_b = {D.1392_67 + 1, +, 1}_2)
(analyze_siv_subscript
siv test failed: unimplemented.
)
(overlap_iterations_a = not known
)
(overlap_iterations_b = not known
)
)
(dependence classified: scev_not_known)
