Description

As of the most recent nightly, rustc 1.42.0-nightly (01a46509a 2019-12-20), our Windows builder in Travis has begun failing. https://travis-ci.com/dtolnay/linkme/jobs/269503401

Both cargo test and cargo test --release fail on Windows with the following:

thread 'test' panicked at 'assertion failed: `(left == right)`
  left: `0`,
 right: `3`', tests\distributed_slice.rs:17:5

The relevant code in the test file is:

https://github.com/dtolnay/linkme/blob/5376b495bcc7587102b35ded301fc87e2e09fb26/tests/distributed_slice.rs#L3-L17

Mentioning @kabergstrom in case this is something you might be able to look into.

Contributor guide

Research direction
Investigate the Windows linker behavior for distributed slices and compare with Linux to find why the test fails on Windows.
