A shellcheck CI job covering every changed shell script
Docker test images for every supported distro, published to the GitHub Container Registry

GitLab CI updated to a current gcc image, with pass/fail behavior brought back in line with GitHub Actions

errno not cleared before PTRACE_PEEKDATA, which could misreport a valid -1 result as an error

readlink(2) silently truncating and reporting a wrong guest path when the host-side target is longer than the caller's buffer
AT_EXECFN naming the loader instead of the traced program, which broke Rust coreutils (uutils) under PRoot
PR_GET_NO_NEW_PRIVS reporting PRoot's own flag instead of the traced program's, which broke sudo-rs
The -P python extension failing to load; WITHOUT_PYTHON not fully disabling it in some build configurations
