"unprintable span" compiler error with improper closure in nom macro

[itaibn]

[Note: I believe that this is probably another instantiation of issue #31089]

The macro chain! from the package nom expects at the end a closure with zero arguments. If the closure has more arguments, the compiler emits the error "internal compiler error: unprintable span". Crate to replicate this error:

Cargo.toml

[package]
name = "bug-test"
version = "0.1.0"
authors = ["xxx"]

[dependencies]
nom = "=1.2.0"

src/lib

#[macro_use]
extern crate nom;

use nom::space;

named!(test,
    chain!(space,
        |x| {x}
    )
);

Error message (full path omitted for privacy):

I just tried to reproduce the bug, but it seems to be fixed in nightly. I noticed you are using rustc 1.6, but #31089 landed after 1.6 was released.

I tested it on nightly, but now I just upgrade nightly and tested it again, and I confirm that it works in this case.
