Confirming same issue here. Presumably needs some additional patching for musl since GETCONTEXT is a glibc invent.
Created attachment 657986 [details, diff] musl.patch Not sure this is the "correct" fix, but it works for me. The meson build does not properly check for musl libc and goes down the ucontext path which doesn't exist. This patch just nukes the path. A proper fix for upstream would be to detect it and fallback to gthread.

You could have it use -Dwith-coroutine=gthread with elibc_musl and leave it as -Dwith-coroutine=auto for everyone else.
Created attachment 659182 [details, diff] Fix with-coroutine setting for musl users I have not fully tested this, but this is the same solution alpine and void linux both use.
Created attachment 659184 [details, diff] Fix musl build Correct syntax, fully tested and working as expected!
