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.

Commencez par la fonction evaluate_function_vector et la déclaration du tableau basis_eval présentées dans le rapport. Reproduisez le shader sur Vulkan avec des valeurs de MAXIMUM_ARRAY_SIZE_NO_STD progressivement plus grandes, en comparant la sortie rendue et le comportement du shader généré. Le travail est terminé lorsque la cause de l’image noire et des artefacts est identifiée et que l’issue dispose d’une correction vérifiée ou d’une limitation documentée.
