SIGSEGV on qr decomposition

[supinie]

I am trying to use the qr decomposition method but am getting signal: 11, SIGSEGV: invalid memory reference whenever I call it.

Cargo.toml:

[dependencies]
ndarray = { version = "0.16.1", features = ["blas", "rayon"] }
ndarray-linalg = { version = "0.17.0", features = ["openblas-system"] }

shell.nix:

with import <nixpkgs> { };
mkShell {
  buildInputs = [
    rustup
    gcc
    bacon
    pkg-config
    openssl.dev
    openblas
  ];
}

Minimal reproduction:

        let mut rng = rand::rng();
        let test = Array2::from_shape_fn((5, 5), |_| rng.random::<i8>() as f64);
        let (q, r) = test .qr().unwrap();

removing the last line, this runs fine.

I've also got this same error attempting to compute the inverse of a matrix, possibly indicating a dependency issue?

Still unsure as to the root cause of why, any help in understanding this issue would be greatly appreciated.
