Checkpointing with Loom

[matanmarkind]

I am trying to debug a loom test which is failing, but I am having issues using the checkpoint.

When I run:
$ RUST_BACKTRACE=full RUSTFLAGS='--cfg loom' cargo +nightly test --test loom --release

I get: " process didn't exit successfully: . . . (signal: 4, SIGILL: illegal instruction)"

When I try to run with checkpoint:
$ LOOM_CHECKPOINT_FILE=fpath.txt RUST_BACKTRACE=full RUSTFLAGS='--cfg loom --cfg feature="checkpoint"' cargo +nightly test --test loom --release

I get a failure to compile due to: "unresolved import serde"

Am I configuring my compilation incorrectly?

Is this a question about use of loom in Tokio, or use of loom for some other project? Also, please include full compiler errors.

Ah sorry about that, fixed and opened an issue in the loom crate.
