[Question] HW5 build failed with sanitizer

[healwon]

I'm in trouble with build failed.
build and test with cargo and cargo --release is done well, but in cargo_asan and cargo_tsan test, it fails to build.

I cannot reason why...anyone know how to solve this problem?

...

running 1 test
test log_concurrent ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 3 filtered out; finished in 2.75s

2. Running AddressSanitizer tests...
Testing growable_array.rs with cargo_asan...
Build failed!
Test failed:    cargo_asan test  --test growable_array smoke
Test failed:    cargo_asan test  --test growable_array stress_sequential
Test failed:    cargo_asan test  --test growable_array stress_concurrent
Test failed:    cargo_asan test  --test growable_array log_concurrent
Testing split_ordered_list.rs with cargo_asan...
Build failed!
Test failed:    cargo_asan test  --test split_ordered_list smoke
Test failed:    cargo_asan test  --test split_ordered_list stress_sequential
Test failed:    cargo_asan test  --test split_ordered_list stress_concurrent
Test failed:    cargo_asan test  --test split_ordered_list log_concurrent
3. Running ThreadSanitizer tests...
Testing growable_array.rs with cargo_tsan --release...
Build failed!
Test failed:    cargo_tsan test --release --test growable_array stress_concurrent
Test failed:    cargo_tsan test --release --test growable_array log_concurrent
Testing split_ordered_list.rs with cargo_tsan --release...
Build failed!
Test failed:    cargo_tsan test --release --test split_ordered_list stress_concurrent
Test failed:    cargo_tsan test --release --test split_ordered_list log_concurrent
Score: 60 / 180

Try

source scripts/grade-utils.sh
cargo_asan test --no-run

Thank you. Actually, I entirely forgot bash source.

I got this result:

So, it seems to be rustc bug.
It is reported in rust-lang/rust#91689, and it said this happens in the latest nightly.
Any way to downgrade?

There are several ways to pin the rust version. https://rust-lang.github.io/rustup/overrides.html

I'll try to fix the grading script in a few hours
