Compilation error in the latest nightly

When I compile my code with the latest nightly I get the following error

This is a regreession - we compile every night with the latest nightly and never ran into this before.

Thank you for the report! It would be useful to bisect the regression using cargo-bisect-rustc to make it easier to figure out what happened and ping the relevant people.

Oh, I just see, this is rustc-serialize. This is a known and expected regression, a patch has been released for rustc-serialize that makes it work again.

Also you should really consider moving off rustc-serialize, it's deprecated and unmaintained (getting patch releases for problems like this is not something expected in the future). Use serde or one of the many other serialization options instead.

Thanks.

It is not a direct dependency.

But I guess these are some old crates I need to upgrade. Will take a look
