Description

Hi.
I did cargo build and suddenly this goes to my console:

error: cannot find attribute `get` in this scope
  --> src/webserver.rs:15:3
   |
15 | #[get("/<name>/<age>")]
   |   ^^^

warning: unused import: `rocket`
 --> src/webserver.rs:4:5
  |
4 | use rocket;
  |     ^^^^^^
  |
  = note: `#[warn(unused_imports)]` on by default

thread 'rustc' panicked at 'failed to lookup `SourceFile` in new context', src/librustc_middle/ty/query/on_disk_cache.rs:456:17
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.44.0-nightly (6dee5f112 2020-04-06) running on x86_64-unknown-linux-gnu

note: compiler flags: -C debuginfo=2 -C incremental --crate-type bin

note: some of the compiler flags provided by cargo are hidden

error: aborting due to previous error

error: could not compile `hard`.

To learn more, run the command again with --verbose.

I gave it another try and this is the backtrace:

I am using today nightly. It was compiling fine before... anyway as I believe that the problem is with panic - I am reporting this bug.
