Hi, I'm having troubles running hfuzz in a CI environment. The error I'm getting:

RUST_BACKTRACE="full" HFUZZ_RUN_ARGS="--exit_upon_crash --iterations 10000 -v --timeout 2 --input coordinatord_fuzz_corpus" cargo hfuzz run send_msg && cd ..

OS: Github Actions with ubuntu-latest rustc version: rustc 1.57.0-nightly (05044c2e6 2021-09-26) cargo version: cargo 1.57.0-nightly (0121d66aa 2021-09-22).

I think the culprit is the rustc version, I can reproduce locally using rustc 1.57, but everything works correctly when I use rustc 1.53.

error still exists if not adding RUSTFLAGS="-Znew-llvm-pass-manager=no"

@syheliel @fgsch @danielabrozzoni after a long while, I'm back to maintaining honggfuzz-rs!

I merged #63 which use sancov-module instead of disabling the new pass manager, if someone thinks it's not the best fix, don't hesitate to tell me :)

@PaulGrandperrin how you find out that with new-pass manager sancov-module will work?
