c2patool returns error about no action in array to stderr and return code 101

[hackerfactor]

This happens with 0.19.0 - 0.25.0. (And probably earlier versions.) Version 0.13.0 worked with this picture.

Result:

Also, the return code ($?) is 101.

May be due to a bad build. My build process:

rm -f Cargo.lock
git pull
cargo update
cargo build --bin c2patool --target x86_64-unknown-linux-musl --release
# Output:
# ./target/x86_64-unknown-linux-musl/release/c2patool
./target/x86_64-unknown-linux-musl/release/c2patool --version
c2patool 0.25.0

While it says 0.25.0, it acted like 0.23.4. When I did a clean git pull in a different directory, it acted correctly and this error did not appear.
