Nightly compilation error due to rustc bug

# rustup run nightly rustc --version
rustc 1.46.0-nightly (3503f565e 2020-07-02)

I tried this code:

https://github.com/paritytech/substrate/blob/master/frame/support/procedural/src/construct_runtime/mod.rs#L31-L425

I expected to see this happen: explanation

Successful compilation.

Instead, this happened:

rustc tells to report a bug, see backtrace.

Meta

rustup run nightly rustc --version --verbose:

Yeah, sorry for that. One of the difficulties of working with a big framework like Substrate. I'll see if I can narrow it down more.

@oli-obk This is still broken. I'm pretty confused because running the test you added in #74102 on the playground shows that it ICEs. Is the test not actually working for some reason?

Edit: Does that test need // compile-flags: --crate-type lib in order to actually check the body of those functions since they are uncalled from main?

Hi @apopiak and @drahnr, have either of you had a chance to upgrade to a recently nightly? I just wanted to confirm this is fixed for you.

I've updated to rust version 1.47.0-nightly (bbebe73 2020-07-22), and tried compiling the crate which was triggering this ICE (sp-arithmetic). I no longer encounter an ICE, the crate compiles successfully.
