Segmentation Fault with musl

[owenthewizard]

If Alpine and/or musl is not supported, let me know and I'll take my issues elsewhere 🙂.

System information

Type	Version/Name
Distribution Name	Alpine Linux
Distribution Version	3.21.2
Kernel Version	6.12.11-0-lts
Architecture	amd64
OpenZFS Version	zfs-2.2.7-1 / zfs-kmod-2.2.7-1

Describe the problem you're observing

During boot, ZFS experiences a segmentation fault. I've not found out what triggers it or any ill effects, but it happens every boot.

Describe how to reproduce the problem

I'm not sure what is causing this, all I can do to reproduce it is reboot...

Include any warning/errors/backtraces from the system logs

I built zfs-lts with --with-debug but it does not seem to have produce any more information...
