module打开后如果不关闭，为什么会出错？有人遇到过么？

我生成了个 动态库，在主程序中加载这个动态库，然后调用里面的接口，如果模块关闭的话是没有问题，如果不关闭的话就会出错
部分代码片段如下
		handle = dlopen ("1.dll", RTLD_LAZY); 
		  rt_kprintf("handle=%u<br>",handle);
             if(handle != 0) 
             {
                  func = (func_sym)dlsym(handle, "getIndex");
                        rt_kprintf("func=0x%x<br>",func);
                  if(func==0 )
                  {
                      oprintf("get err");
                  }
                  else
                  {
                      ret = func();
                      oprintf("get %d<br>",ret);
                  }

dlclose(handle);
             }

如果不进行dlclose的话，后续运行就会进入报错循环- -！，如下：
