Line numbers are truncated in diagnostics.

[kevincox]

Some, but not all, diagnostics are truncating the line number to 2 digits.

Can we remove this truncation? It makes the most visible location for line numbers basically useless.

error[E0560]: struct `game::Table` has no field named `artifacts`
 --> src/game.rs:1452:4
  |
14|             artifacts: vec![None; state.players],
  |             ^^^^^^^^^ `game::Table` does not have this field
  |
  = note: available fields are: `shared_a_data`, `shared_b_data`, `shared_c_data`, `shared_d_data`, `shared_e_data` ... and 3 others

Note that the correct line number is 1452, however next to the code it displays 14.

Note that some diagnostics output the line number correctly:

error[E0063]: missing fields `happiness`, `sanity` in initializer of `game::Game`

     |                        ^^^^ missing `happiness`, `sanity`

Do you happen to have a more minimal example?

[kevincox]

I tried reproducing on the playground with no luck. I'll see if I can get a minimal example: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=47795d540db43935a85384ea7dc91249.

cargo build is enough to reproduce on my project.

[estebank]

What version are you on? Also, is there a repo you can share with a reproduction?

[kevincox]

% cargo version
cargo 1.40.0-nightly (8b0561d68 2019-09-30)
% rustc --version
rustc 1.40.0-nightly (2daa404e9 2019-10-02)

[wesleywiser]

I believe this was fixed the day after that nightly (see #65001).

[estebank]

@kevincox could you rustup update to a newer nightly (or stable) to verify whether this is indeed the same issue which has been already fixed?

[kevincox]

Ah, PEBKAC. I didn't realize that I had pinned an exact version of nightly for that directory. I've updated and the issue doesn't appear to be occurring anymore.
