Hi all,

I have a problem with a memory corruption during glfwTerminate. When I run this program and press esc to exit I get this:

Renderer.destroy: 1
malloc(): memory corruption

The problem goes away if I don't create and destroy the Buffer object so I guess it has something to do with that. But I can't figure out what's wrong. I'm using lwjgl 3.2.1.1 on Linux

All the code (minimized as much as I could):

Thanks in advance

Look at your Buffer.init() method. You free the verticesBuffer twice by calling memFree(verticesBuffer) twice.
    private void init() {
        FloatBuffer verticesBuffer = MemoryUtil.memAllocFloat(vertices.length);
        verticesBuffer.put(vertices).flip();

        vaoId = glGenVertexArrays();
        glBindVertexArray(vaoId);

        vboId = glGenBuffers();
        glBindBuffer(GL_ARRAY_BUFFER, vboId);
        glBufferData(GL_ARRAY_BUFFER, verticesBuffer, GL_STATIC_DRAW);
        memFree(verticesBuffer); // <- FREE HERE!!!

        glVertexAttribPointer(0, 3, GL_FLOAT, false, 0, 0);

        glBindBuffer(GL_ARRAY_BUFFER, 0);
        glBindVertexArray(0);

        if (verticesBuffer != null) { // <- is true
            MemoryUtil.memFree(verticesBuffer); // <- AND HERE!!!
        }
    }


Oh thanks. I totally missed that
