Segmentation fault on Docker

[faibistes]

This minimal program:

using LLama;

string modelPath = @"/model/model.gguf"; // change it to your own model path.

var parameters = new ModelParams(modelPath)
{
    ContextSize = 2048
};
using var model = LLamaWeights.LoadFromFile(parameters);

with these dependencies:

<ItemGroup>
    <PackageReference Include="LLamaSharp" Version="0.10.0" />
    <PackageReference Include="LLamaSharp.Backend.Cpu" Version="0.10.0" />
  </ItemGroup>

Crashes with segmentation fault inside a docker container. The machine has 32 GB of RAM. The program doesn't crash on my windows dev machine, with the same model (codellama)

Hi, it's an unexpected BUG because I know there're people using LLamaSharp in dockers successfully. Which docker image are you using, or it just crashes in any kinds of docker image?

This is the Dockerfile:
