退出前已经执行如下语句来释放资源，但是仍然会报错：

if (pstHandle->pCtx != NULL)
{
      mpp_destroy(pstHandle->pCtx);
      pstHandle->pCtx = NULL;
pstHandle->pMpi = NULL;
}
if (pstHandle->pfrm_grp)
{
mpp_buffer_group_put(pstHandle->pfrm_grp);
      pstHandle->pfrm_grp = NULL;
}

这是用gdb打印的BT信息：

兄弟我也碰到这个问题了，你解决了吗？怎么处理掉这问题

按顺序
mpi->reset(ctx);
mpp_buffer_group_put(group);
mpp_destroy(ctx);
