On arm64 (in case that matters) the wx-break one isn't failing for me. I must
be overlooking something.
The stackpivot jumpback one is also not failing anywhere that I'm seeing.

And since I'm bringing this up, there's also this:
https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/issues/107
Obviously, the link there is for HardenedBSD but the script seems to work the
same on OpenBSD as well.
No, it fails on pinsyscalls.
And to be specific, the jump works, the program doesn't.
