BoundsError when factorizing

[cuihantao]

I ran into a BoundsError when factorizing a sparse matrix, The MWE needs to use the attached CSV file storing the triplets. This might be a wrapper issue because UMFPACK can factorize it,
and a Python-based KLU wrapper provided in KVXOPT also works.

M.csv

Code

using SparseArrays, DataFrames, CSV, LinearAlgebra, KLU

function read_sparse_matrix(M)
    df = CSV.read(M, DataFrame)
    sparse(df[!, "I"], df[!, "J"], df[!, "V"])
end

A = read_sparse_matrix("M.csv")

lu(A) # works


KLU.klu(A)

Output:

BoundsError: attempt to access 431-element Vector{Int64} at index [431:432]

Looks like an error with my printing/display set up. Can you confirm by doing klu(A);?

I'll try to fix it today.

I guess you are right. It doesn't show any error with a semicolon.
