Bad system call (core dumped) on aarch64 (manjaro)

I experienced this crash with the latest release-- I installed from AUR first, and then tried to just check out the latest from this repo (and built using the instructions in the readme). I get the same result either way.
If it's helpful, this is Manjaro ARM 20.08, on a pinebook pro.
Since it's syscall related, I thought perhaps the output of strace might be helpful:
