It is not RC when the package was never built on an architecture.

The buildds where it was tried have either 4 GB or 8 GB RAM.
Which is not the problem when you are running out of address space.

Address space available for a program (like a compiler instance)
on the 32bit release architectures:
2 GB mipsel
3 GB armel/armhf
4 GB i386 built on amd64

With g++ the most common workaround is building with -g1,
I don't have experience how to work around excessive memory
usage in rust.
