您好，我最近在研究轻量级的语义SLAM算法，在Ubuntu20.04和Ubuntu18.04上运行您的代码，总是出现段错误，代码打印如下：

我不知道怎么去解决这个问题，请您不吝赐教。谢谢！

请问解决了，我也是，调整ulimit好像也没什么用

你可以试试将所有 CMakeLists.txt （包括第三方库）中的 -march=native 删掉，重新编译试试。

非常感谢作者的回复，亲测有效，可以顺利运行完了

非常感谢，我已经顺利运行成功！

非常感谢，我已经顺利运行成功！

你好我问一下，我也按照这里面说的删掉了所有的-match=native，比较之前能够运行一会，但是并不能完全运行完，运行一段时间以后就会出现下面的错误，我把段错误打印出来问题是这样的应该怎么解决？
