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

从报告中所示的 evaluate_function_vector 函数和 basis_eval 数组声明开始。使用逐步增大的 MAXIMUM_ARRAY_SIZE_NO_STD 值在 Vulkan 上重现着色器，并比较渲染输出和生成的着色器行为。当黑色图像和伪影的原因被确定，并且 issue 有经过验证的修复或已记录的限制时，即视为完成。

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.
