If code compiles warning-free, then enabling -Werror prevents regressions that would add a new warning. Getting code warning-free, and deciding what set of warnings to be warning-free on, is a harder task, but using -Werror DOES make sense for projects that are already clean for a given set of warnings. > >> I'm surprised you didn't run into this. > > That's quite simple.
