Great. I was wondering about those failures. There’s still something related to LinearOperators though :-(

Let's wait the official release 1.7 to see if we still have the same issues.

The issue is related to the function length of SparseVector{Float32, Int32} that returns Int32 now. I think that it's a bug because we still have Int64 with Float32 dense vectors.

I found the culprit : JuliaLang/julia#39645. It's not a bug.

nrow and ncol attributes of LinearOperators should be Integer instead of Int.
@geoffroyleconte Can you take this into account for the revamp ?
