Root cause is in build_classic_dist_vector -> constant_access_functions which
adds unit distance vector only in case of constant access function. It should
cover invariant cases. Testing a patch. Thanks

Before Richards change we likely gave up on the mismatch in access function
dimensionality for f[b] vs. f[b].e but now we compute a dependence distance
of zero.

So I think the issue is not dependence testing but loop distribution accepting
a
zero dependence distance as OK. Of course dependence analysis is quite useless
here since the accesses are to the same locati
