I've checked out Cargo at rust-lang/cargo@4ce099b and from a clean build directory I get:

$ CARGO_INCREMENTAL=1 cargo +nightly test
...
   Compiling cargo v0.18.0 (file:///home/alex/code/cargo)
   Compiling cargotest v0.1.0 (file:///home/alex/code/cargo/tests/cargotest)

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

Possible duplicate of #39508 ? Same error and it seems like both fail on testing a file called tests/metadata.rs

Choose different name for metadata obj-file to avoid clashes with user-chosen names.

Fixes rust-lang#39585 and probably rust-lang#39508.
Incremental compilation assigns different names to obj-files than regular compilation. If a crate is called "metadata" this can lead to a clash between the root module's obj-file and the obj-file containing crate-metadata. This PR assigns a name to the metadata obj-file that cannot clash with other obj-file because it contains a `.` which is not allowed in a Rust module identifier.
