# Ensure that modifying a crate on disk (without recompiling it)
# does not cause ICEs 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 #86480 for more details
