使用std::make_unique创建的对象，无法检测到泄漏 #21

extern "C" JNIEXPORT void JNICALL
Java_com_xxxx_filament_ObjAssimpLoader_nLoad(JNIEnv *env, jclass, jstring path, jlong nativeEngine) {
    g_meshSet = std::make_unique<ObjMeshAssimp>(*((Engine*)nativeEngine));
    utils::Path filename = env->GetStringUTFChars(path, 0);
    g_meshSet->addFromFile(filename, g_materialInstances, true);
    //人为制造一个内存泄漏对象
    std::unique_ptr<ObjMeshAssimp> temp = std::make_unique<ObjMeshAssimp>(*((Engine*)nativeEngine));
}

大佬，问下，我集成这个工具后，生成report，并没有找到我泄漏的so代码行号，唯一相关的so信息如下：

但是这看起来像是系统编译的内存信息

应该是出错了E/RAPHAEL: invoke failed at xdl_sym 机型是三星 galaxy s8， android 9

阈值设置过大
