<pre>
    I have following github action workflow for my rust project, to get coverage of my tests I'm currently using `cargo-llvm-cov` package with rust nightly toolchain. 

```yml
jobs:
  cargo-llvm-cov:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: dtolnay/rust-toolchain@nightly
      - uses: taiki-e/install-action@cargo-llvm-cov
      - uses: Swatinem/rust-cache@v2

      - name: Generate code coverage
 run: |
          cargo +nightly llvm-cov \
          --all-features \
          --workspace \
          --doctests \
          --lcov \
          --output-path lcov.info

      - name: Upload coverage to Codecov
        uses: codecov/codecov-action@v4
        with:
 token: ${{ secrets.CODECOV_TOKEN }}
          files: lcov.info
 fail_ci_if_error: true

```

Couple of my doctests are not compiling as expected and getting following error on my actions

```
error: aborting due to 1 previous error

Couldn't compile the test.

  = note: PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

```
I don't have any idea, just thinking that rust nightly version and llvm tools chains are not compatible. My versions are as following

```shell
$ cargo +nightly --version
cargo 1.84.0-nightly (cf53cc54b 2024-10-18)
$ cargo llvm-cov --version
cargo-llvm-cov 0.6.13
```
