Description Kyle Evans freebsd_committer freebsd_triage 2024-05-22 17:39:12 UTC 
handlesig calls cleanup(), which is itself not async-signal-safe if `doclean != 0` as it wants to use `snprintf` -- while it notes that it "appears" to be safe on FreeBSD, we should strive to be correct here.
Comment 1 Dag-Erling Smørgrav freebsd_committer freebsd_triage 2024-05-22 18:12:00 UTC 
yeah the comment is wrong, it is no safer on FreeBSD than on any other *nix, but just like on any other *nix it will "appear" to work fine until you manage to trigger a signal at just the wrong time.
