electrs: Bug: Electrs crashes with Illegal instruction when dynamically linked on arm64

Ah, ok, that’s more like it

$ rustc --version
rustc 1.48.0

Cool, happy it worked 😃

Hi @romanz, sorry for lack of response, I’ll check and get back to you asap.

Thanks for all the analysis @romanz . Here is the output of lscpu:

Could you please share rustc --version output?

This is the output I get on the Raspi Debian Bullseye daily image:

$ cat /etc/apt/sources.list
deb http://deb.debian.org/debian bullseye main contrib non-free
deb http://security.debian.org/debian-security bullseye-security main contrib non-free

$ cargo --version

* Rust installed from Debian repositories (cargo 1.46.0)

This is a bit unexpected, because IIUC Debian 11 should have Rust 1.48.0, no?
