Can you attach a full runnable MWE?

and cc @ptiede

Ugh, I had a full MWE that for some reason I didn't post and now I can't find it :(

Now I can't seem to recreate it, but IIRC it can be seen when trying to differentiate a function that has mul! with
a view multiplied by a SparseMatrixCSC going in to a Vector{Float64}, so I was able to reproduce it with a length 3 subarray and a 3x3 SparseMatrixCSC. I'll try again in the morning

I think this is resolved? if not please reopen
