Hi Marius,

I've attached the new v3 for core-updates to this bug report now.

Meanwhile, the bug in mrustc https://github.com/thepowersgang/mrustc/issues/140
apparently has not been fixed yet.  It probably manifests itself because of:

> It seems newer toolchains no longer resolve symbols when the library precedes
> the referencing object file.
> This has always been the case for static libraries, as far as I'm aware, but
> now seems to also be the case for shared libs.
