// Ensure that modifying a crate on disk (without recompiling it)
|
|
// does not cause ICEs (internal compiler errors) in downstream crates.
|
|
// Previously, we would call `SourceMap.guess_head_span` on a span
|
|
// from an external crate, which would cause us to read an upstream
|
|
// source file from disk during compilation of a downstream crate.
|

// See https://github.com/rust-lang/rust/issues/86480
