It's worse, it's "running out of user-land VM space"; the 32-bit
arm ports have a rather hard limit at around 2GB, and that needs
to acommodate the stack as well; I think I've tuned my 32-bit arm
systems to 1.8GB "maximum data size"...

Right, in that case the rust compiler binary is cross-built (on
amd64).

Agreed.
