先上结论：不要使用Archlinux WSL

重要的事情说三遍：

不要使用Archlinux WSL
不要使用Archlinux WSL
不要使用Archlinux WSL

看看Archlinux on WSL? / Other Architectures / Arch Linux Forums中大伙的评论：

It seems to be a set of initial unconfigured packages that you have to configure yourself.
It isn’t Arch, and it isn’t supported by the community.
Or is it maybe something unacceptable about it?
Correct, see http://archlinux.2023198.n4.nabble.com/ … l#a4718292

官方和社区都不支持，那还玩啥？

问题

下面给出一个我在使用ArchLinux WSL中遇到的问题：

当使用python运行一个使用了Cpython的脚本时，引发了segment fault，显示保存信息极少。使用gdb python然后run <script.py>进行调试，然后backtrace：

Thread 1 "python" received signal SIGSEGV, Segmentation fault.

谷歌一圈，解决方案较少，并没有找到合适的解决方案。本来以为可能是使用yay安装到/opt下导致内存限制的问题。但重新在用户家目录下安装miniconda并未解决问题。

之前使用Archlinux也遇到过不少问题，但都可以在Arch Wiki下找到答案，而且很多是由于更新软件包时不看提示信息导致的，这次搜索没有看到明显的有效信息。

既然官方和社区都不支持Archlinux Wsl，那就卸了吧，继续使用“邪恶混沌”的Ubuntu。

（虽然之前在做CMU15-213的Bomblab还是AttackLab时，在Ubuntu时运行程序也有问题，在Debian下没有问题……不过WSL还是要比VMware用着方便，将就着用吧）
