Screen goes black (with artifacts) upon declaration of large array.

I have a fairly complex shader that's doing a lot of numerical analysis on the GPU. One function does this:

pub fn evaluate_function_vector(
        &mut self,
        x: [S; 3],
        degree: usize,
        #[cfg(not(feature = "std"))] coefficients: &[S; MAXIMUM_ARRAY_SIZE_NO_STD],
        #[cfg(feature = "std")] coefficients: &[S],
    ) -> S
    {
        #[cfg(feature = "std")]
        let basis_eval = self.eval(x, degree);

        #[cfg(not(feature = "std"))]
        let basis_eval = {
            let mut basis_eval = [S::default(); MAXIMUM_ARRAY_SIZE_NO_STD]; // THIS LINE!!!!!!!!!!!!
            self.eval(x, degree, &mut basis_eval);

            basis_eval
        };

        let mut res = S::default();
        for i in 0..basis_eval.len()
        {
            let v = basis_eval[i];
            let coeff = coefficients[i];
            res += v.clone() * coeff.clone();
        }

        res
    }

I noticed that different sizes of let mut basis_eval = [S::default(); MAXIMUM_ARRAY_SIZE_NO_STD]; // THIS LINE!!!!!!!!!!!! Caused different behaviours. Small sizes would produce the expected image, sizes of about larger than 50 would create a black image with colour noise sprinkled in, as if rendering a corrupted buffer or uninitialized memory.

I am using the latest cargo gpu to compile my shaders afaik.

I am on Garuda Linux, Vulkan version 1.4.321.

レポートに示されている evaluate_function_vector 関数と basis_eval 配列の宣言から始めます。MAXIMUM_ARRAY_SIZE_NO_STD の値を段階的に大きくしながら Vulkan 上でシェーダーを再現し、レンダリングされた出力と生成されたシェーダーの動作を比較します。黒い画像とアーティファクトの原因が特定され、issue に検証済みの修正または文書化された制限事項があることを完了条件とします。
