@b1zantine Looks like the build is failing, can you double check it's working when you run:

make valkey-unit-tests

[b1zantine]

@madolson make valkey-unit-tests exits with code 0 when there are warnings. The CI workflows failed since we are passing the flag to treat warnings as errors. I have fixed the issues and verified it by running make valkey-unit-tests SERVER_CFLAGS='-Werror'. The CI workflows should succeed now.
