Code

This seems to happen when compiling rustc-std-workspace-core v1.99.0.
I am unsure what Rust code triggers this. I am running the following commands:

# git clone [email protected]:rust-vmm/vm-virtio.git
# cd vm-virtio/fuzz
cargo +nightly fuzz build --sanitizer memory

rustc --version --verbose:

rustc 1.66.0-nightly (01af5040f 2022-10-04)
binary: rustc
commit-hash: 01af5040fdada6ef8f1b749cda798d80a8590b2c

release: 1.66.0-nightly

I've tried the build with other nightly versions as well and it still fails but does not provide a stack trace.

In case this helps out, I've also encountered this ICE when trying to use fuzzing for my own project (cg-jl/sawblade@8be5ef4). The command that I used was different, but causes the same panic in the same line:

Code

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/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.66.0-nightly (6e95b6da8 2022-10-22) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C opt-level=3 -C embed-bitcode=no -Z force-unstable-if-unmarked -C passes=sancov-module -C llvm-args=-sanitizer-coverage-level=4 -C llvm-args=-sanitizer-coverage-trace-compares -C llvm-args=-sanitizer-coverage-inline-8bit-counters -C llvm-args=-sanitizer-coverage-pc-table -C link-dead-code -Z sanitizer=address -C llvm-args=-sanitizer-coverage-stack-depth -C debug-assertions -C codegen-units=1 -Z sanitizer=address

note: some of the compiler flags provided by cargo are hidden
