Code running on local Julia, but failing on CI tests with Ububtu_latest and Windows_latest

The following code is running correctly on my machine

using LinearAlgebra
using ApproxFun
Af = Fun(t -> [0 1; -10*cos(t) -24-10*sin(t)],Fourier(0..2π));
D = Derivative(domain(Af));
ND = [D 0I; 0I D];
Aop = Af - ND;
NA = 322
RW = Aop[1:NA,1:NA]

resulting in a matrix as below

However, the same sequence fails on the Ubuntu_latest and Windows_latest CI test environments with both Julia 1.7.2 and Julia 1.8.0 with the following error message

ERROR: LoadError: MethodError: no method matching blocks(::ApproxFunBase.InterlaceOperator{Float64, 2, ApproxFunBase.ArraySpace{ApproxFunBase.SumSpace{Tuple{ApproxFunFourier.CosSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunFourier.SinSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}}, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, 1, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunBase.ArraySpace{ApproxFunBase.SumSpace{Tuple{ApproxFunFourier.CosSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunFourier.SinSpace{ApproxFunFourier.PeriodicSegment{Float64}, Float64}}, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, 1, ApproxFunFourier.PeriodicSegment{Float64}, Float64}, ApproxFunBase.CachedIterator{Tuple{Int64, Int64}, ApproxFunBase.BlockInterlacer{Tuple{FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}, FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}}}}, ApproxFunBase.CachedIterator{Tuple{Int64, Int64}, ApproxFunBase.BlockInterlacer{Tuple{FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}, FillArrays.Fill{Int64, 1, Tuple{InfiniteArrays.OneToInf{Int64}}}}}}, Tuple{Infinities.RealInfinity, Infinities.InfiniteCardinal{0}}})
(see run information here)

I would appreciate any hint how to manage to run the tests without this error.

quick test on my environment:

I observed that while the CI tests employ the last versions of the underlying packages
(e.g., BandedMatrices v0.17.0, BlockArrays v0.16.16, BlockBandedMatrices v0.11.6), my local test runs with
(BandedMatrices v0.16.13, BlockArrays v0.16.11, BlockBandedMatrices v0.11.1). I wonder if this could be the cause of the systematic failures. Just an idea!

I’ve encountered similar problems with recent versions of BlockArrays etc., avoided by asking Pkg for BlockArrays@v0.16.11. Let’s ask @dlfivefifty if a better fix is in the works.

I tested enforcing v0.16.11 to v0.16.15 and all work. Thanks for the hint.

I opened an issue at 211.

This was caused by something that was technically a bug fix but broke downstream packages. This PR will fix it when merged: Use Block{1} in blockcol/rowsupport by dlfivefifty · Pull Request #95 · JuliaApproximation/ApproxFunBase.jl · GitHub
