Description
Today, we encountered an ICE in our pipelines. You can view it here, and reproduce it by checking out the pull request and running the same commands. A summary of steps is below.
Unfortuntely creating a more minimal working example is something I don't have much time (or the required understanding) for right now - just cargo building the crate by itself works, and repeating the "caused by" command reproduces the error. I'm happy to help otherwise.
Code
# Checkout the pull request
gh repo clone TNO-S3/WuppieFuzz
gh pr checkout 61
# Rustup to nightly
rustup set profile minimal
rustup toolchain install nightly --component llvm-tools-preview --allow-downgrade
rustup override set nightly
# Install the coverage tool
cargo install cargo-tarpaulin
# Crash the compiler :)
cargo tarpaulin --workspace --out Html --output-dir ./coverage-report --ignore-tests --all-features
After some trial and error, it seems the shortest rustc command line that crashes is the following:
/home/erieke/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/rustc --crate-name value_bag --edition=2021 /home/erieke/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/value-bag-1.10.0/src/lib.rs --crate-type lib -Clink-dead-code
In particular, removing -Clink-dead-code leads to a successful compilation.
