Link failure (in alloc, readelf) in proc-macro crate, stable regression 1.44.0 -> 1.44.1

[cristicbz]

This is fixed in 1.45.0-beta.3 and 1.46.0-nightly (f781bab 2020-07-01), but since there's no workaround that I can see, I don't know if this warrants a point release. If not, feel free to close of course.

I reduced one of my dependencies (psl_codegen) which broke in 1.44.1 to the following (available at https://github.com/cristicbz/rust-regression-441 as well):

Cargo.toml:

[package]
name = "regression-441"
version = "0.1.0"

[lib]
proc-macro = true

[dependencies]
error-chain = "0.12.2"

src/lib.rs:

extern crate error_chain;
extern crate proc_macro;

#[proc_macro_derive(Foo, attributes(foo))]
pub fn derive_foo(input: proc_macro::TokenStream) -> proc_macro::TokenStream {
     input
}

With rust 1.44.1 I'm seeing:

Link failure

error: could not compile `regression-441`.

With rust 1.44.0 this compiles just fine:

Removing I-prioritize as the issue is already fixed.
cc @rust-lang/release for the question about having a point release.

[jonas-schievink]

What caused/fixed this?

[cuviper]

I tried your repo on Fedora 32 using upstream 1.44.0 and 1.44.1, and both compiled successfully.

[LeSeulArtichaut]

Maybe related to #73493?

[Mark-Simulacrum]

This looks like an incremental bug perhaps? I don't know that we've found all the cases yet -- I seem to recall a PR by @pnkfelix that suggested that it may have identified the root cause of these?

[pietroalbini]

We're going to have a release in two weeks, so I'm not sure a point release is worth it anyway.

[cristicbz]

I don't think this is incremental, since it happens with [profile.dev] incremental=false too. It also happens right after cargo clean. Looks kinda similar to #69328 , but there's a comment on there that claims it was fixed, so i'm not sure.

[cristicbz]

In a docker container this works just fine, so clearly there's something seriously off with my environment:

FROM ubuntu:20.04
RUN apt-get update && apt-get install -qyy curl binutils build-essential git
RUN curl https://sh.rustup.rs -sSf | sh -s -- -y
RUN ln -s /root/.cargo/bin/* /usr/bin/
RUN git clone https://github.com/cristicbz/rust-regression-441
WORKDIR /rust-regression-441
RUN cargo build

Not sure what could possibly cause this, sorry about the noise I thought I was pretty thorough in trying different versions and reinstalling, but clearly there's something else weird.
