SIGSEGV on qr decomposition #402
Description
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.
