Delays related to 6b73dee

[smoelius]

While reviewing rust-fuzz/afl.rs#392, I noticed some strange behavior regarding 6b73dee.

If you update afl.rs's AFLplusplus submodule to that commit, cargo build seems to think the build script always needs to be rerun.

In particular, clone the afl.rs repo and then run the following commands:

git submodule update
cd cargo-afl/AFLplusplus
git checkout 6b73dee
cd .. && cargo run -- afl --version && timeout 5s cargo run -- afl --version

The last command will exit with a 124, indicating a timeout.

But if you change the 6b73dee to 6b73dee~1, the last command will complete successfully.

I bisected twice with two different ranges, and both landed on 6b73dee.

Any ideas?

that was a weird bug hunt. it was because the manpage that is generated for afl-addseeds was not in .gitignore ...
current dev state fixes that.

Thank you! I can confirm that fixes the problem. Cheers! 🎉
