For me, this fixed debugging with lldb under macOS on AppleSilicon. This is also a general pattern found other code bases, including well-established code bases like the dpkg source code: - https://git.dpkg.org/cgit/dpkg/dpkg.git/tree/utils/start-stop-daemon.c?h=1.22.15#n564 - v1.22.15 is the latest version at time of commit Note that the above link actually compares the return value of waitpid against all negative values (`child < 0`). This was made to pacify static anlyzers in commit 5601b476929a896e1ab67e66e1192d5a90346e75 and is not any more correct than comparison against the documented return value of `-1` for error. - https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=5601b476929a896e1ab67e66e1192d5a90346e75
