It works fine using cargo build locally.

memfd_create requires a newer glibc than what cross 0.2.5 provides by default. You need to use cross from the main branch or specify a newer image to use.

also, be advised that actions-rs is not maintained.

So, either install cross from the main branch with cargo install cross --git https://github.com/cross-rs/cross or specify a newer image in Cross.toml
