Code

There is no special code, I tried to compile libc 0.2.98 as a dependency.

Does this still happen on nightly? It may have been fixed by #86876.

It also panics but the message is another one.
The project is an untouched new one created with cargo new.

Hi,

is there anything new about that? Can I assist in any way further?

Triage: @muellerpeter-pms One way to help right now is to see if you can still reproduce on latest nightly. If you know how to reproduce this without a physical Raspberry Pie, that would also be great.
