UnloadMesh causes double free or corruption on Debian Linux

[pkhead]

Issue description

Calling Raylib.UnloadMesh on my Debian Linux system causes a "double free or corruption" error, forcefully aborting the program.

What follows is the terminal output of a simple Raylib-cs program that calls UnloadMesh(ref mesh).

I have also tested it using UnloadMesh(&mesh). It creates a segmentation fault instead.

Environment

OS: Debian 6.1.69-1, x86_64

OpenGL device information:

• Vendor: AMD
• Renderer: AMD Radeon Vega 8 Graphics (raven, LLVM 15.0.6, DRM 3.49, 6.1.0-17-amd64)
• Version: 4.6 (Core Profile) Mesa 22.3.6
• GLSL: 4.60

.NET:

• Version: 8.0.204
• Raylib-cs: version 6.0.0

Code example

namespace RaylibTest;
using Raylib_cs;

class RaylibTest
{
    static void Main()
    {
        const int screenWidth = 800;
        const int screenHeight = 450;

        Raylib.InitWindow(screenWidth, screenHeight, "raylib mesh unload test");

        Mesh mesh = Raylib.GenMeshPlane(10.0f, 10.0f, 1, 1);
        Raylib.UnloadMesh(ref mesh);
        Raylib.CloseWindow();
    }
}

I have a made an equivalent program in C, which unlike the C# version, runs without error. I linked it against "raylib-5.0_linux_amd64.tar.gz". from Raylib's GitHub releases page.

#include <raylib.h>

int main() {
    const int screenWidth = 800;
    const int screenHeight = 450;

    InitWindow(screenWidth, screenHeight, "raylib mesh unload test");

    Mesh mesh = GenMeshPlane(10.0f, 10.0f, 1, 1);
    UnloadMesh(mesh);
    CloseWindow();
}
