rustc panicked during compilation

[v0y4g3r]

In this CI workflow, rustc panicked while running cargo llvm-cov nextest --workspace --lcov --output-path lcov.info -F pyo3_backend -F dashboard, but all other checks and builds finished successfully.

Affected versions: this panic only appears on rust toolchains after nightly-2024-09-16 (exclusive, it works on nightly-2024-09-16).
