It wasn't clear to me that early_error was correct here, but it seems to work. This code is reachable from `rustdoc`, which is problematic, because early_error panics. rustc handles the panics gracefully (without ICEing or crashing), but rustdoc does not. It's not the first such rustdoc problem, though: $ rustdoc hello.rs --extern std=bad-std error: extern location for std does not exist: bad-std hello.rs:1:1: 1:1 error: can't find crate for `std` hello.rs:1 ^ error: aborting due to 2 previous errors thread '<unnamed>' panicked at 'Box<Any>', /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/libsyntax/diagnostic.rs:151 thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: "rustc failed"', /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/libcore/result.rs:744 thread '<main>' panicked at 'child thread None panicked', /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/libstd/thread.rs:661 |
