It's arm64-specific in the sense that it tries things that I know are
difficult on arm64, such as passing particular kinds of struct as
argument and return value. However, it's supposed to be written in
correct C and should work on every architecture. It's possible that it
has exposed a bug in the arm back end as the calling convention for
32-bit ARM has some of the same complexities. I think I have a 32-bit
ARM chroot somewhere I can test it on so I'll see if I can narrow it
down a bit.
