该问题的根本原因是由于assimp库中的代码在处理顶点数据时可能会造成内存泄漏。为了避免这个问题，我们可以通过自己管理内存来解决这个问题。

以下是解决方法的示例代码：

#include 
#include 
#include 
#include 

struct MeshData
{
    unsigned int VAO;
    unsigned int VBO;
    unsigned int EBO;
    unsigned int numIndices;

    MeshData() : VAO(0), VBO(0), EBO(0), numIndices(0) { }

    ~MeshData()
    {
        if (VAO) glDeleteVertexArrays(1, &VAO);
        if (VBO) glDeleteBuffers(1, &VBO);
        if (EBO) glDeleteBuffers(1, &EBO);
    }
};

void LoadMesh(const char *filename)
{
    Assimp::Importer importer;
    const aiScene *scene = importer.ReadFile(filename, aiProcess_Triangulate | aiProcess_FlipUVs);

    if (!scene || scene->mFlags & AI_SCENE_FLAGS_INCOMPLETE || !scene->mRootNode)
        throw std::runtime_error("Failed to load mesh");

    aiMesh *mesh = scene->mMeshes[0];
    MeshData data;

    glGenVertexArrays(1, &data.VAO);
    glGenBuffers(1, &data.VBO);
    glGenBuffers(1, &data.EBO);

    glBindVertexArray(data.VAO);
    glBindBuffer(GL_ARRAY_BUFFER, data.VBO);
    glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, data.EBO);

    glBufferData(GL_ARRAY_BUFFER, mesh->mNumVertices * sizeof(aiVector3D), &mesh->mVertices[0][0], GL_STATIC_DRAW);
    glBufferData(GL_ELEMENT_ARRAY_BUFFER, mesh->mNumFaces * 3 * sizeof(unsigned int), &mesh->mFaces[0].mIndices[0], GL_STATIC_DRAW);

    glEnableVertexAttribArray(0);
    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(aiVector3D), 0
