During the compilation of your image, do you see any warnings from “sed”? I use a Docker container on an M1 MAC, and I need to modify the Makefile in musllibc to prevent a rootserver crash. This patch bypasses an issue of sed creating a new file. Without it, the seL4 flavor of musllibc won’t compile.

Hello guys,
I'm trying to run sel4 using qemu under macosx, but it looks crash happened(Same steps were done on Ubuntu, but nothing bad happened.).
More info: I'm following the doc here with docker as the build environment: https://docs.sel4.systems/GettingStarted.html
Any tips are appreciated.
