Regression with type inference in a recent nightly affects bail!

[golddranks]

One of the doc tests fails.

The breakage happens between nightlies 668864d9e 2017-02-16 and 536a900c4 2017-02-17.

Thanks!

For the record, the error is https://travis-ci.org/brson/error-chain/jobs/203564573#L385, with this line causing problem. Maybe it's because the Ok(()) is unreachable?

I'm getting this also in recent nightly, but in code that previously worked.
Result<()> seems to be the problem.

What do you mean?

[Emilgardis]

I had an unreachable Ok(()), replacing it with unreachable! fixed it.

[Yamakaky]

Yeah, it's an inference change from the compiler.
