trying to compile a program that has a dependency on this package. It gets stuck trying to compile every time.

I've waited overnight. Still no love.

Docker command is

docker run --rm -ti --platform linux/amd64 -v $(pwd):/workspace rust:1 bash

M1 Mac - v12.5 (21G72) Docker - v4.11.1 (84025)

Hi - I don't have any Mac to try this myself, but if you're getting stuck merely compiling autocfg, not even running it, then this seems like an issue for the compiler. This is not using proc-macros or anything like that which might directly intrude on the compilation process, just plain Rust code -- not even any unsafe!

Hadn’t even thought to talk to the compiler team. I’ll give them a shout. other packages compile just fine tho, so it’s a bit odd that this (tiny no dependency lib) is the thing that breaks it. I’ll report back if I get an answer from the compiler team.

I did get this to work with a fresh image somehow. Can't remember quite how, but the whole rust compilation thing is a little off for me in containers right now, so I've got more playing to do before understanding what is wrong.
