[Question] Test timed out on cargo_asan --release (HW2)

[03psb]

When I ran the grading script, all the other parts are ok but cargo_asan --release part creates timeout issue.

Running with cargo_asan --release... Compiling aho-corasick v1.1.3 Compiling regex-automata v0.4.6 Compiling regex v1.10.4 Compiling cs431-homework v0.1.0 (/home/seongbeen/cs431/homework) Test timed out: cargo_asan test --release --doc linked_listework
Finished release profile [optimized] target(s) in 0.04s Running tests/linked_list.rs (/home/seongbeen/cs431/homework/target/x86_64-unknown-linux-gnu/release/deps/linked_list-94dd7893f5c4a70e)

above is the terminal message for the timeout part. Is this the problem with my environment, or does it mean that I should modify my implementation for performance?

Have you tried running the grading script on the provided development server or gg site? I would suggest you to try this since I've just checked that I don't have any problems on these environments.

If the same problem occurs on these environments, I guess you need to come up with a better solution since we set the timeout to be not too tight if your solution is correct. Below, I attach a part of the log regarding cargo_asan --release that I got by submitting on gg for your reference.

I have to say that if time-out doesn't occur with debug cargo_asan and it occurs with --release, it sounds a bit weird, since release should be faster (but maybe it's compilation time issue).

Actually, optimization of incorrect programs can lead to infinite loops; although it is probably unrelated here.

I tried it on the development server, and it was okay. I kind of forgot the existence of development server. Thank you all for your reply.
