Hello musl team,

I tried getting a core dump but I'm not sure if I'm doing something wrong...

I am able to run:

# apk upgrade busybox --repository=https://dl-cdn.alpinelinux.org/alpine/v3.18/main --repository=https://dl-cd
n.alpinelinux.org/alpine/v3.18/community

and not create a segmentation fault on Alpine 3.17

I will be on Christmas vacation for the next week but when I get back I can try to get additional details.  

Thanks!

Those issues will keep popping up til we fix them, and to fix them we
will need to know exactly what to fix, a backtrace may help with that.
Alternatively we'd need a simple way to reproduce the issue.

I found this following the above issue:
https://gitlab.alpinelinux.org/alpine/aports/-/issues/15167
This issue looks more like a problem in busybox than musl.
