Attempting to run clippy on a single file causes it to crash

[PhilipDaniels]

Example:

cargo clippy runtime_data.rs

results in

   Compiling qork v0.1.0 (file:///data/qork/qork/src/rust/qork)
    error: multiple input filenames provided

    thread 'rustc' panicked at 'Box<Any>', /checkout/src/librustc/session/mod.rs:824:4
    note: Run with `RUST_BACKTRACE=1` for a backtrace.
    thread 'main' panicked at 'rustc_thread failed: Any', /checkout/src/libcore/result.rs:906:4
    error: Could not compile `qork`.

With the backtrace, we get

   Compiling qork v0.1.0 (file:///data/qork/qork/src/rust/qork)
error: multiple input filenames provided

thread 'rustc' panicked at 'Box<Any>', /checkout/src/librustc/session/mod.rs:824:4
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

For what it's worth Clippy doesn't crash anymore:

$ cargo clippy utils.rs
error: Found argument 'utils.rs' which wasn't expected, or isn't valid in this context

USAGE:
    cargo check [OPTIONS]

For more information try --help

$ cargo clippy -- utils.rs
    Checking proptest-arbitrary v0.2.1 (/tmp/clippy/proptest-arbitrary)
error: multiple input filenames provided

error: Could not compile `proptest-arbitrary`.

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

@camsteffen was this resolved or just closed?
If resolved, would you be able to point me to the appropriate pull request?

[camsteffen]

Sorry I don't know when it was fixed.

It still crashes.
user@user-desktop ~/D/P/r/> cargo clippy -- src/main.rs
error: failed to run rustc to learn about target-specific information

Triage: still the same.
